SUMMARY
The discussion centers on the conditions for incompressibility in fluid dynamics, specifically under thermal flows with low Mach numbers (less than 0.3). It is established that the divergence of velocity, represented as Div(V), must equal zero for a flow to be classified as incompressible. This condition is both necessary and sufficient, meaning that if Div(V) is not zero, the flow cannot be considered incompressible. The exchange highlights the clarity needed in defining incompressibility in the context of viscous and conductive thermal flows.
