WebThe Sherwood number ( Sh) (also called the mass transfer Nusselt number) is a dimensionless number used in mass-transfer operation. It represents the ratio of the convective mass transfer to the rate of diffusive mass transport, [1] and is named in honor of Thomas Kilgore Sherwood . It is defined as follows. where. L is a characteristic length ... 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 (less than 0.2); free-stream turbulence, end effects, channel blockage, free convection, …
Churchill–Bernstein Equation
WebThe Churchill–Bernstein equation is a correlation and cannot be derived from principles of fluid dynamics, The equation yields the surface averaged Nusselt number, which is used to determine the average convective heat transfer coefficient. WebIn 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. truffles chicken
