Numerical Simulation of Turbulent Impingement Cooling
Volume 3: Heat Transfer; Electric Power; Industrial and Cogeneration, 2001Simulations of turbulent impinging jet heat transfer for different nozzle configurations using Reynolds averaged governing equations and two-equation turbulence models have been conducted. The considered nozzle configurations are a square-edged orifice and a pipe exit.

Numerical Simulation of Impinging Jet Cooling
2010 14th International Heat Transfer Conference, Volume 5, 2010This paper presents a technique for heat transfer prediction of impinging jet cooling of internal combustion engine piston based on numerical simulation in ANSYS CFX. This technique implies the simulation of the hydrodynamics of the interaction between cooling oil jet and moving piston.

Fundamental Behaviors and Limits of Impingement Cooling
Twenty-Third Annual IEEE Semiconductor Thermal Measurement and Management Symposium, 2007Direct fluid impingement on a surface has been shown to generate very high performance heat transfer. Several systems have been designed and commercialized incorporating impingement cooling, such as single and multiple jets, sprays and combined jet-drain arrays.
