Courant-Friedrichs-Lewy(CFL) number plays an important role in detremining stability of the system. For transient state, when diffusion term is involved,CFL term is defined as CFL=alpha.(dt/dx^2) where alpha is Thermal Diffusivity when dx term is increased by a factor of 2,we need to decrease the value of dt by factor…

The main objective of this project is to examine that given wheel arc area of the car fender will pass the European standards or not. As per European standard,clearance length L between tire and wheel arc area of the fender at 5 cross-sectional areas such as at SA-SA,SB-SB,SC-SC,SD-SD and SE-SE as shown in the below image…
