Classification of CFD methodsīefore we jump in, let us take a look back to the 18th century. Because there has been significant development in terms of hardware, the importance of CFD analyses only continues to increase. In CFD, the Navier-Stokes equations (NSE) are discretized and solved on a computer. Over the past few years, simulations with CFD methods have become an integral part of the design process of new products. Predicting the fluid flow for a new product is a hard task, we feel you! Especially when design cycles are short and many different variants of a product must be assessed in terms of the fluid flow, it is not possible to rely solely on experiments. If you are reading this, chances are that you are one of these engineers. Importance of CFDĪll kinds of engineers deal with fluid flow while working on their specific applications, be it a gearbox, a heat exchanger or the diffusor of a race car. Instead, we will focus on the basic numerical understanding of these approaches. Since this post is meant to be read on the way to work, during breakfast, lunch, coffee or after work, we will avoid using any mathematical formulations. Furthermore, we want to give you some insights into the most favorable fields of application for each method presented. This article will give you a basic understanding of the most prominent methods used in Computational Fluid Dynamics (CFD) and touch on some of the newcomers, like the Smoothed Particle Hydrodynamics method.
