This paper experimentally investigates the effect of surface roughness on flow and heat transfer characteristics in circular microchannels. All test pieces include 44 identical, parallel microchannels with diameters 0.4 mm 10 length. The is Ra = 0.86, 0.92, 1.02 μm, Reynolds number ranges from 150 to 2800. Results show that has remarkable effects performance behavior transfer. It found Poiseuille Nusselt numbers are higher when relative larger. For behavior, friction factor increases...
A variety of turbulence models were used to perform numerical simulations heat transfer for hydrocarbon fuel flowing upward and downward through uniformly heated vertical pipes at supercritical pressure. Inlet temperatures varied from 373 K 663 K, with flux ranging 300 kW/m2 550 kW/m2. Comparative analyses between predicted experimental results evaluate the ability respond variable thermophysical properties It was found that prediction performance is mainly determined by damping function,...
This study empirically investigates the influences of several parameters on surface morphology and etch rate in a high-aspect-ratio silicon etching process. Two function formulas were obtained, revealing relationship between controlled results. All experiments conducted an inductively coupled plasma system, using Bosch The tested trenches' width ranged from 15 to 1500 µm their depth 50 500 µm, which covers nearly all typical sizes micromechanical devices practical applications. are chamber...
Owing to the limited supply and pressure margin in air system, a cooling technique providing efficient heat transfer with lower flow loss is highly desirable for gas turbine blades. Microscale ribs have promised be potential candidate. In this work, large eddy simulations are implemented reveal scale effect of micro on near-wall turbulent transport channel. Considering mechanistic study practical applications, both single-rib rib-array arrangements studied wide range dimensionless...
Emulsions have been applied in a number of industries such as pharmaceutics, cosmetics, and food, which are also great scientific interest. Although aqueous emulsions commonly used our daily life, oil-in-oil (o/o) play an irreplaceable role view their unique physics complementary applications. In this paper, we investigate typical behaviors organic droplets surrounded by medium (o/o emulsions) with different functional groups controlled the AC electric field. Droplet can be catalogued into...
