An experimental study is made of heat transfer in the condensation zone and during boiling in the heating zone in heat pipes with intensively heated ends. Generalized relations are presented.doi:10.1007/BF00831928Yu. F. GortyshovV. I. Maratkanov...
In this study, we model the heat transfer mechanism for a single nucleate vapor bubble which then expands to an elongated bubble during evaporation in a microchannel. The model is a logical mix of empirical correlations and analytical models and is defined for the two steps of bubble growth ...
An experimental study on evaporation heat transfer has been conducted in horizontal smooth tube with pure DME and CO2/DME mixture. Mixing CO2 to DME causes the degradation of heat transfer coefficients. Evaporative heat transfer of DME is inferred to be dominated by convective evaporation heat transf...
Experimental investigation of heat transfer in evaporation and condensation processes on capillary surfacesThe article describes experimental investigations of the evaporation and condensation of water and ethyl alcohol on wetted threadlike capillary surfaces of materials with different thermal conductivities....
An experiment was carried out to investigate the characteristics of the evaporation heat transfer and pressure drop for refrigerant R-134a flowing in a horizontal small circular pipe having an inside diameter of 2.0 mm. The data are useful in designing more compact and effective evaporators for var...
Focuses on a study that examined experimentally the evaporation heat transfer coefficient and pressure drop for refrigeration R-134a flowing in a plate heat exchangers. Overview of the refrigerant loop used in the experiment; Background information on the plate heat exchangers used in the experiment;...
Finally, droplet evaporation is very important in heat-transfer applications4. For instance, a recently reported jumping-drop technique exploits superhydrophic surfaces to induce the motion of evaporating-condensing droplets for “hotspot cooling”, and is a promising heat-management technique in ...
The SolidWorks model of the present MAPLE technique was exported through LiveLink™ for SolidWorks® in order to identify the present bottlenecks of the process. Addressing the identified issues, a new cooling technology was designed to assist the MAPLE technique. COMSOL Multiphysics® enabled...
