Churchill and bernstein equation

WebW. J. Minkowycz has included themes like Condensation, Convection and Mass flux in his Heat transfer coefficient study. The subject of his Mass flux research is within the realm of Thermodynamics. His Pressure drop research is multidisciplinary, relying on both Nusselt number, Churchill–Bernstein equation, Vortex and K-epsilon turbulence model.

WebJun 19, 2024 · 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. WebA single comprehensive equation is developed for the rate of heat and mass transfer from a circular cylinder in crossflow, covering a complete range of Pr (or Sc) and the entire range of Re for which data are available. This expression is a lower bound (except possibly for RePr < 0.2); free-stream turbulence, end effects, channel blockage, free convection, etc., may …
