Featured CFD Consulting Case Studies

zero energy ventilation

CFD Analysis of Natural Ventilation  

The newly designed green building is intended to be a beacon in sustainability design and energy efficiency, for which the ventilation strategy is being designed as a low energy free cooling system.
CFD studies were carried out to assess the feasibility of different design features, such as venturi effects, natural convection, solar chimney and wind sensitivity.

Thermal cooling system

Thermal Cooling System

Our client installs Server Houses under their transmission antennas to generate mobile coverage for their customers. The Servers generate 5kW of thermal heat and the cooling dissipation system is not optimized. In order to cut down electricity expenses and improve energy efficiency, an energy simulation and CFD study were carried out to optimize the system.
Several cooling devices and configurations were analyzed. Eventually, a wind-induced extraction system over the exhaust of the server was implemented as the most energy efficient one.

Other Featured CFD Consulting Case Studies

thermal comfort mapping

Thermal Comfort Mapping

Our client wants to remodel the small and needed to address the thermal comfort level reached in some spots under the strong prevailing wind current flow in the region. Dynamic thermal comfort study was carried out, along with comfort and radiation analysis in the enclosed terrace areas.
Different set-ups of windscreens and flowerpots were designed and evaluated in order to maximize interior comfort conditions (along with greenhouse effect, climatization of spaces and circular wind currents created by the mall´s circular shape.

enclosure design optimization

Enclosure Design Optimization

As part of the climate, strategy different enclosure options were systematically analyzed in order to minimize energy use and maximize the energy efficiency near fully-automated logistics center.
Specific 3D CAD models were created to analyze the energy performance and thermal comfort characteristics of different climatization options. Special efforts were made to maximize comfort times in working areas.

Windshield De-icing CFD Simulation

This is the new competency development project with an Automotive client. The objective of this CFD consulting project was to predict the ice melting pattern on the windshield at 15 min,20 min, 25 min & 30 min. 95% of the ice has to clear within 25 mins.
Our CFD engineers modeled the full cabin along with HVAC for this analysis. Initially, this simulation was done at steady state once the flow has been developed the simulation is switched to a transient case and the flow equations will be frozen and energy equation only switched on. We successfully developed this competency development project and my CFD results were 98% correlated with experimental results.

Numerical Simulation of Transonic Flow over Complex Configurations

An opensource CFD solver SU2 is used for simulation and Pointwise was adopted as the mesh generation tool.
Simple wings like HIRENASD to complex structures like whole fighter aircraft (LCA) were studied. Plots of various flow parameters are in agreement with experimental results.
With this validation, the analysis is carried out for critical values and thus helped in carrying out safe experimental tests.

Development of Code within SU2 for Unsteady Fluid Flow with user Specified Motion

The objective is to incorporate user-defined motion for mesh morphing in unsteady flow analysis. A code is developed within SU2 in C++ language. Here the surface mesh is changed according to the equation that user has fed into the solver. Then volume mesh is morphed, this, in turn, alters flow field.
This code developed helped in specifying an equation of motion of choice and use it for fluid flow analysis.

Numerical Studies on Fluid flow past Transversely Oscillating Rectangular Cylinder of Different Aspect Ratio

For the last few decades, engineers dealing with the design of bridges, offshore structures, electronic chips etc. have been studying the fluid-structure interaction of the bluff bodies. The fluid-structure interactions are studied by a common approach wherein the body is forced to oscillate with a predefined motion that actually resembles the flow-induced vibrations.
For the present CFD consulting study, an in-house SUPG-FEM algorithm based on non-inertial frame approach is employed. In the present algorithm, the effect of the non-inertial frame is represented by a simple source term in the transverse momentum equation. It facilitates computational convenience by avoiding the re-meshing of the whole domain that is required if a fixed inertial frame were used instead. Accordingly, the rectangular cylinder was forced to vibrate for various configurations such as the Aspect Ratio, Reynolds number based on the depth of the cylinder.
The frequency ratios chosen for the study are 0.5, 0.75, 1.0, 1.5 and 2.0. The oscillating amplitude ratios considered for the cylinder are 0.1, 0.2 and 0.3. The pressure and the surface tangential component of the cylinder acceleration play an important role in the vortex formation and shedding.
As the flow attains constant periodicity, vortices with an alternate sense of rotation are shed behind the rectangular cylinder. The influence of the cylinder vibration on the wake patterns, phase plane, lift force, drag force etc. are presented and discussed. It is observed that the force coefficients are high at harmonic frequency ratio for lower amplitudes, as the amplitude increases the maximum value shifts to superharmonic case.

DFSS Studies for Floor Ducts

The objective of this CFD consulting project is to predict the thermal heat loss from the building floor ducts by using the different type of insulation materials with different insulation thickness. Overall for this CFD simulation study, L1 to L12 cases was done and each case has four different subsequent iterations, totally 48 iterations were done. This project got a best DFSS award.

CFD Analysis for an IP Duct

The objective is to minimize the pressure drop. By using the CFD studies, our engineers were able to have minimized the pressure drop less than the maximum limit.

Store Separation Analysis for Mirage aircraft using DFBI model with unsteady Euler CFD Solver

The objective was to calculate the separation distance after the release of the store from an aircraft. Native DFBI model in StarCCM+ is used for the simulation of before mentioned study. An overset mesh is generated for the same purpose and investigation is done.

Numerical Analysis on Effect of Aspect Ratio on Fluid Flow Characteristics Past a Rectangular Cylinder

The objective of present work is to explore, the effects of different aspect ratios (AR) and Reynolds number (Re) on unsteady laminar fluid flow past a stationary rectangular cylinder. For this purpose, equations governing laminar fluid flow are solved in a Cartesian framework using an in-house code based on Streamline Upwind/Petrov-Galerkin finite element method (SUPG-FEM). Velocity profiles, instantaneous vorticity contours and streamline patterns were used to identify different vortex shedding regimes. In downstream of the cylinder, unique vortex shedding regime which is associated with stretching and stronger rotation of vortices is observed. It is not observed for the other bluff bodies like circular and elliptical cylinders. Further, the results of aerodynamic force calculations such as lift, drag values, and Strouhal number are discussed in detail. The present study can be applied to analyze fluid flow characteristics of MAVs, flow past tall buildings, flow past rectangular and design of the electronic chips.

Case Study

For example, a client had a flow-control value in a large water storage reservoir that under standard flow calculations would have required an expensive design modification to handle the estimated forces.
Our CFD consulting analysis revealed that the manual hand-calculations were overly conservative and that the existing, budgeted design was more than adequate.
Following our recommendations, the client went forward and the valve is operating per specifications.
We know from our prior CFD service work on wind loaded structures, that given subject to the same flow physics, the valve structure would perform similarly.
