the present study is based on a global analysis of the effect of the channel orientation on the two-phase heat transfer coefficient, which was performed by collecting 5408 data points from independent published works that include flow boiling, flow condensation and heated gas-liquid flows at variou...
Two-Phase Flow, Boiling, and Condensation This text is an introduction to gas-liquid two-phase flow, boiling and condensation for graduate students, professionals, and researchers in mechanical, nuclear, and chemical engineering. The book provides a balanced coverage of two-phas... Ghiaasiaan,S ...
Recently, there has been much research on the boundary-layer condensing flow because of its connection to condensation heat transfer in porous media, see Plumb [24], Majumdar and Tien [25] and Chung et al. [26]. The previous theoretical studies neglected the vapor flow in order to render ...
These are of interest by thermal research community because of the cellular structure and have gas-filled pores inside a metal matrix. Due to the uniqueness in their structure, they exhibit good performance in boiling heat transfer because of the properties such as higher specific surface area, ...

You can find some values of this coefficient in the literature for particular cases, type of flow,... Antoine thanks for replying I want to simulate evaporation and condensation of water. How can I simulate evaporation and condensation process using Lee Model in Openfoam? Thanks, ...
enhanced 10-15 fold over a corresponding bare surface. A combination of extended microsurface area and large numbers of stable re-entrant nucleation sites are responsible for the improved performance. The external tube surface is also enhanced for condensation by the provision of flutes on the ...

Also, the higher inlet subcooling delays the CHF because condensation enhances heat absorption by liquid. Sign in to download hi-res image Fig. 34. The principal modules of the Flow Boiling and Condensation Experiment (FBCE) on the Optics Bench of the Fluid Integrated Rack (FIR), and the ...
and models of maximum bubble slide diameter and maximum bubble condensation diameter were proposed[30]. Furthermore, a model for predicting bubble coalescence rate during subcooled flow boiling was proposed[31]. Based on a large amount of experimental data, machine learning was used to better analyz...
