This study is focused on the and development of a gas-to-liquid heat pipe exchanger (HPHE) based numerical experimental analysis. Stainless steel pipes were installed inside in form three equilateral triangles, staggered into hexagonal configuration to simulate waste recovery from hot exhaust gas water flow. The first main aim this was 3D design analysis, which used create calculate effect simi...

heat exchangers are the critical components of refrigeration and liquefaction processes. selection of appropriate operational conditions for cryogenic recuperative heat exchanger and expansion valve operating in joule-thomson cooling system results in improving the performance and efficiency. in the current study, a straightforward procedure is introduced to design an efficient joule-thomson co...

in the presented research, heat transfer of a mobile electrolyte alkaline fuel cell (afc) (which the electrolyte has cooling role of system) has been considered. proper control volumes of system with specific qualification have been chosen. consequently, heat and mass transfer in control volumes have been assessed. considerations on them and contributed models lead to approve a double tube heat...

A manufacturing process plan was developed for a welded condenser utilizing a sintered wick. Electronic devices have progressed to the point where new designs are limited by the thermal management system used to ensure safe operating temperatures. Coupling the effects of high surface area of multiple condensers, the low thermal resistance of loop heat pipes, and the increased dissipation rates ...

the objective of the present study is the synthesis of mwcnt-tio2 hybrid nanostructures by solvothermal synthesis method with ticl4 as precursor. the heat transfer enhancement due to the use of mwcnt-tio2 nanofluid was investigated. as-prepared hybrid materials were characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem). the results showed that mwcnts were uniformly dec...

BACKGROUND Ground source heat pumps is a building energy conservation technique. The underground buried pipe heat exchanging system of a ground source heat pump (GSHP) is the basis for the normal operation of an entire heat pump system. METHODS Computational-fluid-dynamics (CFD) numerical simulation software, ANSYS-FLUENT17.0 have been performed the calculations under the working conditions o...
