Research on the Flow Control of a Piston Cooling Nozzle
Scientific Programming, 2022 The flow rate of a piston cooling nozzle is usually adjusted by changing the parameters of convergent length and inner diameter of the nozzle in engineering. However, the influence law and quantitative relationship between the flow rate and them are not clear.

Cancellation of the Heating Piston Effect by Convective Enhancement of a Cooling Piston Effect [PDF]
International Journal of Thermophysics, 1998 This work brings new insight to the question of the piston effect, which has been found to be the main cause of temperature equilibration in the vicinity of the liquid–vapor critical point under weightlessness conditions. The thermalization process of a near-critical fluid confined in a cavity and submitted to local heating is modeled with special ...
