This paper presents a fully dry assembly method to obtain densely packed arrays of parts from 400-800μm in size. This approach shows promise for enabling formation of a module of n and p type materials optimized for micro scale thermoelectric cooling performance. INTRODUCTION Inertial force (mass of the assembled parts) plays a critical role for part alignment and orienting in a dry microassemb...

In this study, we examine the driving mechanism for atmospheric overturning circulation on dry, tidally-locked rocky planets without condensation of water vapor or other species. We find that main process is radiative cooling CO2 (or non-condensable greenhouse gases) rather than warming stellar radiation. Stellar radiation ultimate but not direct mechanism. Due to combination uneven distributio...

• Complete exergoeconomic optimization of binary power plant that includes cooling tower using variable metric minimization method. The research proposed a cost rate equation for wet and introduced sustainability index (SI) eight different working fluids. This study investigated complete comparison dry-cooled plants. Simple organic Rankine cycles (ORC) Olkaria geothermal field in Kenya isobutan...

Abstract Cutting energy must be reduced in order to make machining processes more eco-friendly. More was expended for the same amount of material removed, hence a higher specific cutting (SCE) implies inefficient removal. Usually, type coolants or lubricants affects SCE, needed cut given volume material. Therefore, present work deals with study SCE turning Ti–3Al–2.5V alloy under green cooling ...

Wind affects adversely the cooling tower thermal performance. A field investigation was carried out to study the thermal performance of Heller cooling towers under wind conditions, involving measurement of wind velocity and its direction around the cooling tower, and obtaining water flow rates and temperatures at the cooling tower inlet and outlet. Results show that air suction at the tower top...

temperature restrictions on aqueous effluents dictate that streams with a temperature higher than the permitted level needed to pass through cooling systems to reduce the effluent temperature before discharge. in this study, by considering the grouping design rules based on pinch technology, an optimum design for a distributed effluent cooling system, has been developed. a counter-flow wet cool...
