Chilton and Colburn J-factor analogy — Chilton–Colburn J factor analogy is a successful and widely used analogy from heat, momentum, and mass transfer analogies[1] . The basic mechanisms and mathematics of heat, mass, and momentum transport are essentially the same. Among many… … Wikipedia
Reynolds analogy — relates turbulent momentum and heat transfer. The main assumption is that heat flux q/A in a turbulent system is analogous to momentum flux τ, which suggests that the ratio τ/(q/A) must be constant for all radial positions.The complete Reynolds… … Wikipedia
Churchill–Bernstein equation — 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.[1] The need for the equation arises from the inability to solve the… … Wikipedia
