Heat transfer and pressure drop in a reciprocating blind duct with swirls generated by a lateral entry jet

Study on the influence of coconut oil on flow pattern and pressure drop of two-phase swirl flow

“…If the swirler is the coil spring, the measured pressure drop is 1.5 times that of the nonswirl. In 2011, Chang et al 33 carried out the swirl ow pressure drop characteristics experiment with the swirl ow of the piston cooling channel of marine diesel engine. The experimental results show that the existence of swirl ow signicantly improves the heat transfer capacity of the system, and the pressure drop coefficient of the swirl ow is signicantly higher than that of the non-swirl ow.…”
