A new cooling scheme is proposed where the primary working fluid flowing through a micro-channel heat sink is pre-cooled to low temperature using an indirect refrigeration cooling system. Cooling performance was explored using HFE 7100 as working fluid and four different micro-channel sizes. High-speed video imaging was employed to help explain the complex interrelated influences of hydraulic d...

Active cooling technologies such as heat pipes, loop heat pipes (LHPs), thermosyphons, loop thermosyphons (LTSs), and pumped singleor two-phase coolant loops require specialized modeling treatment. However, these 1D ducted systems are largely overlooked in 3D thermal modeling tools. The increasing popularity of CFD and FEM models and generation of analysis data from 3D CAD data are strong trend...

The main objective of this work was to demonstrate computationally that realistic human hearts can be cooled much faster by performing conjugate heat transfer consisting of pumping a cold liquid through the cardiac chambers and major veins while keeping the heart submerged in cold gelatine filling a cooling container. The human heart geometry used for simulations was obtained from three-dimensi...

Adjusting operating temperature of the engine in the steady state and during warm-up improves fuel consumption and reduces engine emission through higher operating temperatures. Also it can improve thermal comfort by faster cabin heater performance. Thermal fluid analysis by 1-D simulation is an effective tool for studying the control of the entire cooling system and optimization of engine perf...

the performance of a γ-al 2 o 3 /n-decane nanofluid shell-and-tube heat exchanger in a biomass heating plant is analyzed to specify the optimum condition based on the maximum heat transfer rate and performance index for wide range of nanoparticle volume fraction (0–7%). compared with pure          n-decane, the obtained results in this research show that by using γ-al 2 o 3 /n-decane nanofluid ...

Burns caused by hot coolant from the reservoir of motorfarming tricycles have not been reported previously. We performed retrospective studies of such cases in 126 patients with complete records in rural areas of China. The majority of victims were unmarried (59.5%), young (<40 years, >20, 55.6%), and male (male to female ratio 9:1). The burn accident occurred mostly during the busy seasons of ...

This paper deals with the study of various machining process and show the effect of different cutting parameters on the properties of material. There are several important factors in the product quality which are surface finish, cutting temperature, tool life and coolant quality. The use of coolant generally causes life of tools and it also maintains work piece surface properties without damage...

Objective. The aim of the work is to study use nanofluids as heat carriers increase efficiency removal in energy facilities. To solve this problem, materials domestic and foreign scientific articles, conferences dissertations on subject were analyzed. Numerous publications, including those cited international databases Web Science Scopus, indicate that topic focus modern science. However, despi...
