Multiple jet impingement cooling

Journal of Thermophysics and Heat Transfer, 1993
Experiments 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 ...

MEMS Impinging-Jet Cooling

Micro-Electro-Mechanical Systems (MEMS), 2000
Abstract This paper presents an experimental investigation on MEMS impinging jets as applied to micro heat exchangers. We have fabricated MEMS single and array jet nozzles using DRIE technology, as well as a MEMS quartz chip providing a simulated hot surface for jet impingement.

Impingement Cooling by Multiple Asymmetric Orifice Jets

Journal of Heat Transfer, 2022
Abstract This study presents impingement cooling from a flat plate by multiple asymmetric jets. Such jets are discharged through blunt-edge inline orifice holes with a thickness-to-diameter ratio of t/Dj = 0.5 and a jet-to-jet spacing of T/Dj = 4.0, at the Reynolds number of 20,000.

Mist/Steam Cooling by a Row of Impinging Jets

Volume 3: Heat Transfer; Electric Power; Industrial and Cogeneration, 2001
Closed 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 ...

Impinging jet cooling on concave surfaces

AIChE Journal, 2004
AbstractThe 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 ...

Submerged liquid jet impingement cooling

2011 IEEE 13th Electronics Packaging Technology Conference, 2011
In this paper, submerged liquid jet array impingement is proposed as a solution for the thermal management of the high performance electronics. Experiments were done using a submerged jet array of 285 nozzles of 0.5 mm diameter spaced 5.5 mm apart, machined on a 5 mm thick nozzle plate, with an impingement height of 3 mm.
