Thin liquid wall fillTIs flowing under the influence of high-velocity turbulent gas streaIllS were studied for the purpose of obtaining an understanding of the Illechanics of filIll cooling. Conditions which insure liquid-filIll attachIllent to solid surfaces without loss of unevaporated liquid to the gas streaIll when siIllple radial-hole injectors are used were found; the IllaxiIlluIll allowa...

Output performance of a thermoelectric-based automotive waste heat recovery system with a nanofluid coolant is analyzed in this study. Comparison between Cu-Ethylene glycol (Cu-EG) nanofluid coolant and ethylene glycol with water (EG-W) coolant under equal mass flow rate indicates that Cu-EG nanofluid as a coolant can effectively improve power output and thermoelectric conversion efficiency for...

Investigation of the electrochemical deterioration mild steel in rice husk agro-waste developed nano-coolant is presented this study. Corrosion rates versus concentration are presented. Linear polarization test data was also covered. Mild coupons were immersed different concentrations (ten and control as a reference) nano-fluid for period 24, 48, 72, 96, 120, 144 168 h. rate calculated based on...

Increasing the power and reliability of microelectronic components requires heat sinks with greater transport performance. This study investigates hydraulic performance a silicon sink under constant flux 100 W/cm2 liquid coolant running through parallel microchannels. The coupled transfer walls coolant, modelled as single-phase fluid, is examined over Reynolds number range 100?Re?350 for micro-...

Abstract In manufacturing sector, looking for a balance between environmental and technical efficiency taking into account productivity is mandatory. Some sectors, such as the biomedical also needs to consider cleanness inherent prosthesis processes avoiding pathogens transfer human body, that is, neither chemicals, bacteria, nor uncontrolled metals can be introduced during surgical interventio...

1 Fellow, ASME Abstract A semi-empirical model for conduction/convection in a thin “fin-like” porous wall of arbitrary composition and thickness is developed. The model assumes one-dimensional conduction in the porous matrix and one-dimensional flow of the coolant through the wall. Closed form solutions are obtained for a uniform composition and thickness porous wall having an insulated tip. An...
