A Quick Overview

In the course of 3 months, you will learn the application of Computational Fluid Dynamics theory on internal flows and especially focus on simulating the Centrifugal Pump, Superchargers and Turbochargers.

You will work on the following software throughout the course,
  • CONVERGE STUDIO: To setup the cases and providing BCs
  • CYGWIN/CMD: Command-line window to run the simulation
  • PARAVIEW: Post-Processing software (to post-process the results
The problem helps you understand important concepts like how fluid flows through turbomachines and where the fluid separates as well as the recirculation zone where it gets generated. You will also delve deep into how the shape of blades and shape of outlet runners affect the results and plot performance curve for all applications. The advantage of working with Converge is that the meshing is automated, saving you loads of time and effort.

At the end of this course, you will be able to set up any internal flow problem, clean up any complicated geometry, and most importantly model turbulence. The course also trains you to set up the case for multi-phase. Other important theories that you will apply are concepts of Turbulence (RANS), Cavitation and CHT.

COURSE SYLLABUS

1CONVERGE Studio Module

In this module, you will learn how to set up a CFD simulation using CONVERGE CFD. We will provide step-by-step instructions on the following:
  • CAD import and cleanup
  • Decomposing the model into boundaries and volumetric regions
  • Inputting valve timing
  • Choosing turbulence and combustion models
  • Running the case in a parallel environment
  • Post-processing

2Surface Preparation

In this module, we will elaborate on surface preparation in complete detail. Here you will learn the following:


  • Setting up the moving boundaries
  • Geometry cleanup

3Regions and Initialization

In this module, you will learn the following concepts:
  • Initializing pressure, temperature and species concentration in different flow regions
  • Disconnect triangles
  • While setting up the case, one will come across complex problems where there will be different zones where the value for any thermodynamic properties like Pressure or temperature will be different and set up the case accordingly, CONVERGE provides a very good feature of creating a region (volumetric region) in which there will be particular value for the pressure, a temperature that user will provide according to his needs.
  • A very good example of the application of regions and initialization is a SHOCK TUBE problem in which there are 2 chambers filled with fluid, one at high pressure and other at low pressure and these 2 regions are separated with the help of the diaphragm. Now to set up such cases, a feature of Regions and Initialization seems to be really important and useful.
  • After creating 2 regions, we need to provide initial values to both regions accordingly and this is how students will learn to create volumetric regions.


4Turbulence Modelling

In this module, students will learn how turbulence is modelled and simulated in a state-of-the-art CFD solver. You will learn about the different classes of turbulence models and understand their merits and demerits.

  • Here, students will learn about the RANS approach to model turbulence.
  • You will get to appreciate the mathematics involved behind RANS and will learn the derivation part as well.
  • You will learn various turbulence models available like (RNG k-ε, k-ω SST etc) and understand which model is suitable for which application.
  • Mostly, RNG k-ε suits best for Internal flows and k-ω SST suits best for external flows.


5Cavitation Modelling

In this module, you will learn how Cavitation can be simulated. We will be focussing on the Volume of Fluid Method (VOF). You will also learn about VOID FRACTION which is the basis of the VOF method.





Projects Overview

Centrifugal Pump

Highlights

The objective of this project is to simulate flow through a centrifugal pump and obtain the pump performance curve. The performance curve is the plot of Volume flow rate Vs. Total pressure drop. It is a tool that shows how a pump is going to behave in terms of head and flow. The performance curve defines the range of possible operating conditions for the pump. With the help of this curve, we can determine the size of the impeller, NPSH and the efficiency required to pump against a particular head and at a given flow rate. You will work on transient simulations so that you can capture the flow physics.

Supercharger Flow

Highlights

The objective of this project is to simulate flow through a supercharger. Superchargers are characterized by complex flow structures and tiny gaps. By applying a robust meshing methodology, the student can validate the mass flow rate and outlet temperatures accurately.

Turbocharger Flow

Highlights

The objective of this project is to simulate flow through a Turbocharger and obtain the performance curve. You will be running transient simulations to capture the flow Physics.
 

2D Cavitation

Highlights

The objective of this project is to look for the Cavitation zone by using the Volume of Fluid (VOF) method and plot the Cavitation zone length with respect to the pressure difference. The study of Cavitation is very important as it affects mass flow rates coming into a cylinder via fuel injectors. Cavitation occurs because of a sudden drop in pressure heads and this occurs because of abrupt change in flow area. When the flow area suddenly decreases, it creates a zone of low pressure or separation zone. When the pressure becomes lower than the vapour pressure of the fluid, fluid instantaneously vaporizes into the gas phase and this affects the injector properties in terms of delivering the required fuel flow rate and this can further affect the combustion and emission performance. And that’s why it’s very important to look at Cavitation in automotive applications. In the HVAC or Turbomachinery world, Cavitation is extremely important in rotating devices.
