In convective heat transfer, the Churchill–Bernstein equation is used to estimate the surface averaged Nusselt number for a cylinder in cross flow at various velocities. The need for the equation arises from the inability to solve the Navier–Stokes equations in the turbulent flow regime, even for a Newtonian fluid. When the concentration and temperature profiles are independent of one another, the mass-heat transfer analogy can be employed. In the mass-heat transfer analo… WebAug 1, 1995 · Zukauskas, A., 1987, “Convective Heat Transfer in Cross Flow,” in: S. Kakac, R. K. Shah, and W.
