Multiphase Flow Simulation

Effects of Coal Feeding points on Hydrodynamics of the Fluidized bed.

A fluidized bed is a device used in the process of thermal power generation. This project aimed to optimise the coal feeding points of a fluidized bed. 3D CFD was used for modeling the hydrodynamics. A two-phase Euler model was used to model the fluidized bed. To reduce the mesh complexity porous medium was used to model the distributor plate. This decreased the mesh density significantly. Standard K-epsilon turbulence model was used to model the turbulence with wall function. The differencing scheme used was the Quick for the momentum equations and Presto for pressure term.
The work was done through two milestones. The first milestone involved modelling the geometry using the drawings given by the client. This was performed using SolidWorks. The second phase included meshing the domain, using ICEM-CFD tool. Structured hexahedral elements were generated. The CFD calculations were performed using Fluent.
Two members did this work. My contribution included meshing, solving, post-processing and report writing. Calculated the inertial and viscous resistance of the porous medium. Re-meshed to achieve right wall Y+. Provided a detailed report on the project methodology and findings. Studied various coal feeding point and reported on the best coal feeding configuration.

Analysis of Flue Gas Flow in The Piping of Circulating Fluidized Bed Boiler

This multiphase flow simulation is more about the analysis of fluid dynamics which is focused on the interaction between two phases while they were engineered to be separated in the end. The obstacle was around on how to separate the mixed solid particle on turbulent gas flow. Hence, the effort was to make the flow to be laminar first. For this simulation, the area that I applied based on the following categories are CFD flow analysis, fluid dynamic analysis, multiphase flow simulation, and turbulent flow simulation.

Multiphase Flow Simulation of Column

This Multiphase Flow simulation involves a Turbulent Flow condition, to get proper distribution of solid material present in the column with the incoming turbulent flow to fluidize the bed of solid material.
Euler model was used to define both phases with species transport equations to incorporate reactions, specific turbulent parameters were given on the basis of the geometry of the column.
the conclusion was, With the help of UFD to retain solids in the column I was able to get the proper fluidized bed with std. k-e turbulence model.

CFD Analysis to design a patent Pending Nozzle to Fill the Automatic Transmissions

Automatic Transmissions need to be filled with a certain amount of oil before being shipped off to the final assembly plant. The current nozzles in the transmission plant were designed for the previous generation of transmissions. Thus they were causing the oil to leak out as the oil jet was impinging on new parts.
A CFD model of the complete transmission with all the internal components was built using ANSA and Star CCM+. Using the Volume of Fraction (VOF) method which is used to simulate Free Surface flows, different nozzles were tested to prevent this oil leak. Finally, this new nozzle design was tested on all new upcoming transmission designs.
The new nozzle correlated with testing to show that the oil leak issue was solved and could be used for multiple transmission designs. By having a common nozzle design, the project saved Ford Motor Company $1.5 Million in Tool Change.

CFD Simulation and Optimization of a Snow Throwing Jet (Multi-Phase flow)

Objective- Test different rotating blades that have different shapes to optimise the jet spread and jet thickness
Methodology – StarCCM+, Python code to run code in Batch Mode
Outcome – After analyzing 10 different blade designs, the client was provided with two selected design from the simulation. The blade provided by us was tested by the client, the performance was improved.

Conjugate-Heat Transfer Analysis of Heated/Automobile Fin

The fluid is air and solid material used is aluminum with the standard flow and material properties are chosen. The coupled flow model with K-epsilon turbulence model is selected for analysis.
Heat transfer variation in solid-fluid junction showed proportional temperature variation with respect to fluid velocity. This also helped in analyzing conduction in solid and natural convection in surrounding fluid.

CFD Analysis of Draining of highly Viscous Liquid in Float based Dosage System   

The objective of this project was to understand the draining of highly viscous liquid from the container which designed uniform upper section connected to the tapered lower section with a small tubular connection. Using CFD simulation, draining of liquid of different viscosities in different configurations of tubular connections (no. of tubes and diameter of the tube) are analyzed. DesignModeler was used for model cleanup and fluid volume extraction. ANYSYS Meshing was used for meshing and FLUENT was used for CFD analysis.
