Numerical Design and Analysis Techniques for Flow Field

4 Numerical Design and Analysis Techniques for Flow Field 

CFD-based techniques date back to the early 1960s, and the first commercial CFD software became available in the early 1980s. Since then, research and development into CFD has transformed the techniques from a theoretical approach 

1 Governing Conservation Partial Equations Used in Computational Fluid Dynamic Approach 

Gas flow in a reaction is considered to follow the principles of conservation of momentum, energy, and total mass. These parameters are used to simulate flow behaviour through numerical solutions of differential equations. The general derivation and form of these equations are given in standard references [53-55], and these principles and related equations are briefly introduced below. 

Within CFD, mass is conserved, that is the rate at which mass enters a volume element equals that mass leaving the element in any steady state process. The mass continuity equation is important and is hence developed by formulating the relationship between the mass flowing into and out of a stationary volume element
