  Flux  Limiters:  We can study the shocks and discontinuity that arises in the Engineering problems,particularly Fluid Dynamics problems by applying numerical schemes. It can be said that Low Order Schemes are usually stable but quite dissipative around the points of discontinuity. On the other side, High…
