Condensation in a Square Minichannel: Application of the VOF Method [PDF]
Heat Transfer Engineering, 2013 A number of steady-state numerical simulations of condensation of R134a at mass fluxes of 400 kg m−2 s−1 and 800 kg m−2 s−1 inside a 1-mm square cross section minichannel are proposed here and compared against simulations in a circular cross section channel with the same hydraulic diameter.

Numerical calculations of the thermal deformations of the rectangular minichannel walls
EPJ Web of Conferences, 2016 This paper analyzes the thermal deformations of the walls of a rectangular minichannel. The distribution of temperature on the walls and the local coefficients of heat transfer between the heated wall and the boiling fluid were determined on the basis of
