Multiple jet impingement cooling
Journal of Thermophysics and Heat Transfer, 1993Experiments were performed to study the effect of nozzle rotation, flow rate, degrees of subcooling, number of jets, and velocity on the heat flux in jet impingement cooling using deionized distilled water. The heat flux is a strong function of the flow rate and degree of subcooling, attaining a maximum value of the order of 600 W/cm at the highest ...

Mist/Steam Cooling by a Row of Impinging Jets
Volume 3: Heat Transfer; Electric Power; Industrial and Cogeneration, 2001Closed loop steam has been chosen for cooling airfoils in heavy frame Advanced Turbine Systems (ATS) to improve efficiency. Enhanced cooling by the use of mist is considered to have potential to augment cooling by internal steam alone. Water droplets generally less than 10μm are added to 1.3 bar steam and injected through a row of four discrete round ...

Optimal design of impinging jets in an impingement/effusion cooling system
Energy, 2014Abstract To design an impingement/effusion cooling system that realizes the lowest thermal stress in an impingement/effusion cooling system, we conducted thermal analysis and optimization using a second-order response surface method. The optimal impinging jet system was based on four design variables: the spacing between the impinging jets and ...

Impinging jet cooling on concave surfaces
AIChE Journal, 2004AbstractThe numerical modeling of jet impingement cooling onto a semicircular concave surface is reported. The performance of two‐equation turbulence models (such as the k–ε model) is evaluated vs. the Reynolds stress model proposed. The Reynolds‐averaged momentum and energy equations are solved together with equations for the turbulence models, using ...
