The resulting number of cells in the volume meshes ranged from 9 million to 84 million, depending on the fluid volume occupied by each constricted geometry. non-dimensional heat input. Pe. The Reynolds number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities. Its physical significance can be inferred from its definition. Ability of a fluid to transport momentum by molecular means Pr Ability of that fluid to transport energy by molecular means = = Gases typically have Prandtl numbers in the range . Q . Conventionally, the left side of the channel was considered the inlet and the right side the outlet. The heat conduction equations above were developed using an energy balance on a differential element inside the medium, and they remain the same regardless of the thermal conditions on the surfaces of the medium.
