Flow regime based heat transfer correlation for R245fa in a 3 mm tube [PDF]
241 heat transfer measurements for R254fa were conducted. The heat transfer coefficient was determined for a smooth stainless steel tube with an inner tube diameter of 3 mm. The experiments were conducted for five mass fluxes (100, 300, 500, 700 and 1000

Comparison of dns of compressible and incompressible turbulent droplet-laden heated channel flow with phase transition [PDF]
In this paper a turbulent channel flow with dispersed droplets is examined. The dispersed phase is allowed to have phase transition, which leads to heat and mass transfer between the phases, and correspondingly modulates turbulent flow properties.

Three-dimensional MHD flow and heat transfer in a channel with internal obstacle [PDF]
The magnetohydrodynamic flow and heat transfer of a liquid metal in a channel past a circular cylinder with walls of non-uniform conductivity were investigated. The applied magnetic field was transversal to the forced flow (x-direction) and coplanar with
