Effects of surface tension reduction on wind-wave growth are investigated using direct numerical simulations of air-water two-phase turbulent flows. The incompressible Navier-Stokes equations for air and water sides are solved using an arbitrary L...
<p>EGR cooler is a heat exchanger that reduces NOx emissions and improves fuel consumption of cars. Up to now, fin shape Vortex generator have been used to improve the heat transfer performance, but in recent years, raised dimple shape have attrac...
<p>Heat exchangers are installed in the cycle of car air conditioners to improve the fuel efficiency of automobiles. This higher performance of the internal heat exchanger leads to further improvement of fuel consumption and reduction of the influ...
<p>Boiling heat transfer using immiscible liquid mixtures is an innovative cooling technique for high-heat-density electronic devices. Immiscible liquid mixtures which are composed of more-volatile liquid with higher density and less-volatile liqu...
<p>The suppression of wind waves by surfactants and other chemicals has been confirmed for a long time. Because of the complexity of the phenomena, the suppressing factors and the mechanism are not completely clear. In this experiment, using three...
