1.	The difference scheme to be used in the hybrid system is chosen by evaluating the ____________(a) Local Peclet number(b) Global Peclet number(c) Reynolds number(d) Nusselt numberThe question was asked in a national level competition.This intriguing question comes from Convection-Diffusion Problems in section Convection-Diffusion Problems of Computational Fluid Dynamics
Answer» The CORRECT choice is (a) Local Peclet number The explanation: The central differencing SCHEME works WELL with low Peclet numbers and the upwind scheme works well for high Peclet numbers. So, the differencing scheme to be used in this METHOD is chosen using the Peclet number.
