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.

A most common complaint often cited by computational fluid dynamics practitioners is the generation of a good quality computational mesh and is estimated to be costing about 70% of the entire simulation cycle. Though much progress has been made in terms of algorithm accuracy and speed over the last three decades, generating grids step for complex, real world computations still remains the most time consuming and least reliable component of CFD simulation process. Meshless methods thus provide a viable alternative to grid-based flow computation as they are supposed to not require the conventional grid structure and thereby relieving the many issues specifically related to grid generation step. This blog shall provide you an introduction and update about the popular meshless methods available today.

Though CFD has been widely used as a standard and well established engineering design analysis and optimization tool, the turbomachinery flow simulation still remains one of the challenges to handle. The typical reasons that make them so are the very complex nature of geometries and flow physics encountered in turbomachines. The following phenomena make turbomachinery flows extremely intricate and difficult to model for CFD simulation studies:

Hello Friends, its being a long time I haven't shared any new information on User Defined Functions (UDFs) available in ANSYS Fluent. Well that may make you think that UDFs are so tough to create, that this person took so long to write his second experience (blog) on UDF! Yeah, it’s funny, but let me tell that this is not the case with me, they (UDFs) are actually so interesting …and huge time & manual effort saver …and productive …and… I can go on and on if I start listing down all the plus points of using UDFs in Fluent. So, long story made short, I was fully enjoying past few months in learning and using this UDF & Scheme programming knowledge to Automate CFD studies in ANSYS Fluent.
