In the heavy-frame advanced turbine systems, steam is used as a coolant for turbine blade cooling. The concept of injecting mist into the impinging jets of steam was experimentally proved as an effective way of significantly enhancing the cooling effectiveness in the laboratory under low pressure and temperature conditions. However, whether mist/steam cooling is applicable under actual gas turb...

In this study, thermoelectric generation with impinging hot and cold nanofluid jets is considered computational fluid dynamics by using the finite element method. Highly conductive CNT particles are used in water jets. Impacts of Reynolds number nanojet stream combinations (between (Re1, Re2) = (250, 250) to (1000, 1000)), horizontal distance jet inlet from device (r1, r2) (?0.25, ?0.25) (1.5, ...

This study numerically investigated the atomization characteristics of misaligned impinging jets, with misalignment ratio ê ranging between 0 and 0.2, by employing volume fluid method an adaptive mesh refinement algorithm. The results show that droplet Sauter mean diameter varies non-monotonically reaches minimum value, which implies best performance, at ê=0.1 under operating conditions concern...

Sweeping jets are oscillating generated by fluidic oscillators, i.e., devices designed to produce an oscillation of the flow without use any moving parts (Raghu, 2013). A typical configuration such consists expansion chamber connected a high-pressure supply via converging nozzle and provided with feedback channels. The motion in is triggered inherent instability sustained rate across Recently, ...

The purpose of the present study is to clarify the heat transfer characteristics with multiple jet impingement aiming at the highly efficient cooling performance. In the study, we investigated the effect of injection parameters on circular jet array impingement heat transfer. As we focus on interference among the adjacent impinging jets, tests are mainly conducted at the minimum crossflow condi...
