Momentum Source Term in SIMPLER Algorithm

Hello all,
I am trying to write a code based on SIMPLER algorithm of Patankar by following the book of Versteeg. There is no source term for my study, I am imposing the exact values of the boundary points on a staggered grid. Do i still need to define any value to the b (momentum source term) in the momentum equation or it is just needed for implementing boundary conditions? Any idea will be greatly appreciated, Thanks in advance |

If there is no force for example say gravity etc, then b is 0.

Thank you very much Arjun,
I am using air as working fluid, so I will neglect the weight of the fluid. Then the two dimensional momentum equation for this case would be:
