چکیده
The sustainability index, waste energy ratio and improvement potential of a staggered air jet impingement on the spherical protrusions roughened absorber plate were derived for present study to evaluate exergy losses irreversibility in system. experimental analysis was carried out selected parameters: relative streamwise pitch, spanwise pitch diameter hydraulic ratio. flow Reynolds number ranged from 4000–18,000. augmentation Nusselt friction factor compared smooth surface 4.9 12.4 times, respectively. statistical correlation developed determined maximum thermohydraulic performance parameter exergetic efficiency be 3.02 3.87%, magnitude found 1.0347, 0.962 10.84, respectively, entire range tested parameters. A cost also performed cost-effectiveness solar thermal system with without turbulent promoters.

Thermal Performance of Jet Impingement with Spent Flow Management
The present study proposes novel micro-jet impingement heat sink with effusion holes for flow extraction. The design consists of impingement nozzles surrounded by multiple effusion holes to take away the spent fluid. A three-dimensional numerical model is used for steady, incompressible, laminar flow and conjugate heat transfer for the performance analysis of the proposed design. The computatio...

متن کاملSolar Thermal Collector System Modeling and Testing for Novel Solar
Solar cookers are aimed at reducing pollution and desertification in the developing world. However, they are often disregarded as they do not give users the ability to cook after daylight hours. The Wilson solar cooker is a solar cooker designed to address this problem by converting solar energy and storing that energy as heat in the form of molten salt (lithium nitrate). This thesis involved r...

متن کاملThermal-hydraulic performance of convective boiling jet array impingement
jet impingement boiling is investigated with regard to heat transfer and pressure drop performance using a novel laser sintered 3D printed jet impingement manifold design. Water was the working fluid at atmospheric pressure with inlet subcooling of 7 o C. The convective boiling performance of the impinging jet system was investigated for a flat copper target surface for 2700≤Re≤5400. The result...
