Fluid Dynamic Analysis

The fluid Dynamic analysis is an area of study that has been having been extensively researched by physicists and CFD companies to understand its immense power and analyze the physical effects of Fluid flow in our engineering designs during the rendering of our CFD consulting services. CFD flow analysis is a Flow simulation methodology which can be used during our CFD services for a fast and effective virtual CFD simulation of Heat transfer and Fluid (liquid or gas) flow behavioral pattern either around or through a product design understudy. It is based on this accurate CFD Fluid dynamics flow simulation software model that our CFD consulting engineers at BroadTech Engineering can have a better understanding and more accurate CFD modeling of specific physics of the computational fluid analysis, such as

1. Fluid Dynamic Forces
2. Deriving correlation between specific Liquid or gas with the performance of a specific engineering prototype design
3. Analyzing thermal temperature distribution using CFD thermal analysis
4. Modeling of building indoor air flow.

How Does Fluid Dynamic Analysis Works

The use of fluid flow simulation methodology in engineering design fundamentally involves the solving of physics equations which govern fluid flow motion and forces.

What is Computational Fluid Dynamics (CFD)?

Computational fluid dynamics (CFD) is the application of physics, mathematics, and computational Fluid Dynamic simulation software tools to accurately Simulate and Visualize

1. Flow behaviors of gas or liquid
2. Physical Effects of the Fluid flow on the specific engineering design as it flows past or around the object.

Why is Computational Fluid Dynamics (CFD) Necessary?

As the governing equations for most practical real-world cases of fluid flow behaviors are relatively complex, such fluid dynamic equations can rarely be solved analytically by humans alone and in most requires the use of Numerical methods and the Computation power of CFD simulation software tools.
Thus, this use of Numerical analytical methods and Engineering software simulation tools refers to Computational Fluid Dynamics (or CFD analysis).

Features & Benefits of Fluid Dynamic Analysis

A major proportion of fluid flow dynamics analysis challenges faced by industries in the past are solved using Computational Fluid Dynamics (CFD) methods

Engineering Insights & Cost-Saving Benefits

When this Computational Fluid Dynamic analysis is involved early in the engineering design development process, it literally allows engineering design teams to get their design right the first time, thereby helping to avoid unnecessary tooling rework, delays in project schedules and saving of project development cost.
All these benefits make fluid dynamics analysis an integral part of most engineering design process in most companies today

CFD Fluid dynamic simulation helps to greatly simplify the analysis of Fluid flow behaviors as it enables the validation of various new design iteration with no need for fabrication of costly prototypes.
In often cases, the Fluid dynamic analysis can be relatively complex, where it involves dynamic flow behaviors such as

1. Transfer of Thermal heat temperature
2. Mixing
3. Unsteady
4. Compressible Flows

Without such a Fluid dynamic simulation software tool, the analysis of such flow behaviors can be time-consuming & costly

We can simulate a range of fluid flow behaviors and Physical flow models to offer you deeper engineering insight into your design behavior. This allows you to get your design right the first time early in the engineering development phase, thereby helping to accelerate the rate of innovation.

Fluid Dynamic motion can be accurately Simulated and Analyzed using governing Fluid dynamic equations under specific fluid continuum conditions, where the fluid density remains relatively constant at the region of focus
* Note that in an environment such as in upper atmosphere or in a vacuum space, the continuum condition can be invalid as rarefied flows can occur due to low pressure.

Navier-Stokes Equations

Computational fluid dynamics simulation is derived based on the Navier-Stokes equations which govern the fluid flow motion and fluid forces.
These Navier-stokes equations which are derived from Newton’s second law of motion are physics equations describe how the velocity, pressure, temperature, and density of a moving fluid are correlated.
The surface forces involved in the fluid motion are contributed by pressure acting on the fluid and shear forces due to viscosity

Fluid Compressibility

Fluid compressibility is another category of fluid flow behavior.

1. Incompressible Fluid Flow

If a Fluid flow is incompressible, the effect of pressure on density is negligible and can be ignored.
This also allows the density can be assumed as a constant value to greatly simplify the analysis.
In such scenarios, the fluid flow behavior can be easily solved by continuity and momentum equations alone
*Note

● if a fluid flow is taken as incompressible it effectively rules out the study of shockwaves.
● Buoyancy-driven fluid flow, such as Natural convection cannot be solved using the incompressible fluid flow assumption as/because density variations are the driving force behind the fluid flow motion.

2. Compressible Fluid Flow

A compressible fluid flow assumption has to be adopted for scenarios such as

● Fluid flow Mach number (Ratio of the flow velocity to the local speed of sound) exceeds 0.3
● Fluid is subjected to very large pressure changes

This includes examples such as the study of supersonic airflow which exceed the speed of sound, where the flow is commonly characterized by Shock waves and large Pressure ratios

Type of Fluid Flow Regime

Before fluid dynamic analysis can be carried out, we must determine the type of fluid flow regime that we are analyzing

● Compressible Fluid Flow or incompressible Fluid Flow
● Mach number of the Fluid flow
● Non-Laminar Turbulent Fluid Flow vs Simple Laminar Fluid Flow (determined by Reynold’s number)
● Steady Fluid Flow or Unsteady Fluid Flowmotion

Inviscid Flow

Inviscid flow is an analysis scenario where the fluid flow is idealized, where the effects of viscosity are ignored.
However, in order to have an accurate analysis of real Fluid dynamic phenomena, it is necessary to take into account the viscosity of fluids. This is due to the creation of viscosity fluid boundary layers which heavily contributes to the generation of Eddie currents or Flow separates as well as pressure and frictional losses

Fluid Viscosity

One fundamental material property which concerns fluid motion behavior is the Fluid viscosity
Frictional Flow Shear Forces
Fluid viscosity is a result of frictional forces arising from the interaction between Fluid motion and the solid wall boundaries containing the fluid. This frictional force, also known as Shear force acts in opposition to the fluid flow motion
This frictional shear forces arising from fluid viscosity can be classified into either Turbulent or Laminar flow forces

1. Laminar Flow

In laminar flow, the fluid flow motion behavior moves in layers (ie. lamina) and appears smooth
limited to small and very regular geometries

2. Turbulent Flow

In turbulent flow, the fluid flow pattern is largely Chaotic and contains occurrence of Eddies and intermixing between the fluid layers
Complex due to the highly chaotic nature

Reynolds number

Reynolds number is a standard number used for differentiating the between a Laminar and Turbulent flow regimes
It is a measure of the relative ratio of the fluid motion inertia forces in comparison to the viscous or shear forces resisting the fluid flow motion.
Most Fluid flow behavior that occurs in real-world applications are largely turbulent flow
