This chapter discusses heat transfer during boiling and condensation. Boiling and condensation most often occur together in real processes. The vapor from the boiler is compressed and passed through a condenser. This is usually constructed from a bank of finned tubes placed at the back of the refr...
Boiling and condensationThermal resistanceHorizontal smooth tubeArea fractionA heat transfer analysis of phase change processes, combining boiling and condensation has been applied to a closed heat pipe. Experimental tests and numerical modeling have been carried out on U-type horizontal smooth heat pipe...
Boiling and condensation in heat transfer equipment : presented at the Winter Annual Meeting of the American Society of Mechanical Engineers, Boston, Massachusetts, December 13-18, 1987 sponsored by the Heat Transfer Equipment Committee (K-10), the Heat Transfer Division, ASME : edited by E.G....
Boiling-condensation heat transfer in ultrathin flat heat pipes are complicated and difficult to observe. In this study, a visualization experiment and simulation analysis in an ultrathin limited enclosed space were carried out. Width of the ultrathin enclosed space was 1 mm, with anhydrous ethanol...

This paper experimentally presents the influence of gap size on boiling and condensation co-existing phase change heat transfer characteristics in small confined space. The confined space gap is a closed phase change chamber that consists of a heating copper block whose top is an extension surface ...
On the other hand, nucleate boiling process of a single bubble was simulated using the MARS (Multi-interface Advection and Reconstruction Solver) including a non-empirical boiling and condensation model. The grid size and time step in the simulation were 30-60 ???m and 10 ???s, respectively...
The effect of the filling ratio and inclination angle on boiling and condensation heat transfer of the two-phase closed thermosyphon (TPCT) was experimentally investigated using water as a working fluid. The TPCT has the inner diameter of 25 mm and consists of evaporator, adiabatic and condens...
The overall heat transfer performance, shell side and tube side heat transfer performance of the new three-dimensional finned tube are experimentally investigated in condensation and boiling conditions. In addition, the influence of fin parameters on condensation and boiling heat transfer is investigated ...
