In recent years, there has been growing interest by various engineering product companies to perform design simulation studies at different stages of product development to compete in the market. This has consistently resulted in increased requirement of skilled CFD resources and proving to be a very good career opportunity for engineers aspiring to make a career in the interesting domain of heat transfer and fluid flows. However there seems to be a widespread confusion in the student community as to what skills are desired by these industries for a fresher to qualify.
As all of CFD, in one form or the other is based on the fundamental governing equations of fluid dynamics i.e. the continuity, momentum and energy equations these are called as the equations speaking physics. They are the mathematical statements of the three physical principles that govern fluid dynamics, hence it becomes very important to derive and discuss these equations. The current blog is motivated to review the very basis of governing equations understanding their physical meaning before actually deriving them.
Understanding the turbulent behavior of fluids is one of the most fascinating, forbidding & critical problems in all of classical physics. Turbulence is omnipresent, as most of the fluid flows are turbulent in nature right from the microscopic level at interior of biological cells to the macroscopic scales of the geophysical and astrophysical phenomenas including planetary interiors, oceans and atmospheres that represent the dominant physics of turbulent fluid flows.
Having already gone through our blog series of CFD modeling of turbomachinery, wherein we discussed about the CAD Repair and Grid Generation we shall now explore the different solver models available in a commercial software package. CFD modeling of flows within systems containing moving components (e.g. turbomachines) are performed by resorting to moving reference frames (MRF). There are a number of both generalized and specialized commercial softwares available that apply moving reference frames for both translating and rotating systems. MRF approach finds application in a wide range of systems like turbomachinery, mixing equipment, electric motors and generators, rotating passages & land and air vehicle motions. In the current blog we shall try to understand applying MRF model for turbomachinery explained with the help of a simple test case.
Any academic degree, let it be bachelors or masters, ends with a project work. The project work is one of the most critical parts of any academic degree. It is so important that it always decides what’s going to be next for the student. Let it be higher studies or industrial job, the whole career path (at least the starting point of that path) is based on the project work.
