... effectiveness. The study explores the flow structure, vortex interactions, and the effects of blowing ratio (BR = 0.2–2.0) and momentum flux ratio (MR = 0.3–3.5) on film cooling. Additionally, the formation and dynamics of the anti-counter rotating vortex pair (anti-CRVP) in a fan-shaped arrangement...

.... To overcome this problem, the rotary matrix of the preheater can be modeled using a porous media approach. But a thorough investigation is required to evaluate its performance. In this work, rotary air preheater simulations were carried out by applying a porous media approach. The effects of different...

.... The experimental results show that the hexagonal ZnO/water nanofluid was superior toward enhancement of car radiator thermal performance comparing to that of SiO 2 NPs. In addition, at 6.5 liter/min and 45 °C, the improvements of car radiator effectiveness due to using SiO 2 and ZnO based water nanofluids...

.... Tests planned under a multi-level factorial experimental design were carried out to evaluate the effects of the volumetric fraction of the gold nanoparticles, the volumetric flowrate of the working fluid, and the inlet temperature of the hot fluid (water) on the SHCT heat exchanger effectiveness...

...Mallikarjuna Rao Pabbisetty; B. V. S. S. S. Prasad A novel mist-assisted air film cooling scheme is proposed by Li and Wang (2006, “Simulation of Film Cooling Enhancement With Mist Injection,” ASME J. Heat Transfer, 128 , pp. 509–519) to increase the film cooling effectiveness of a gas turbine...

...Zhe Zhang; Sunil Mehendale; Shengnan Lv; Hui Yuan; JinJin Tian Fluid flow maldistribution causes deterioration of heat transfer as well as pressure drop penalty in heat exchangers. A test bench was set up to investigate the effect of different header designs on air-water flow distribution in plate...

... systems (FLESs), one for parallel-flow and another for counter-flow double-pipe heat exchanger (DPHE). Such FLESs are capable of predicting the exit temperature of heat carrier fluids and its effectiveness in an accurate manner. In total, 96 sets of experiments have been conducted for parallel and counter...

... and the land area needed for its installation. The objective of the present study is to investigate the effect of different backfilling materials (low cost and locally available) on the thermal performance of GAHE system using a small-scale laboratory experimental setup. Seven different backfilling materials...

... and helical-coil pipe layouts. After 12 h of continuous operation, the effectiveness of the EATHE system with U-shaped, slinky-coil, and helical-coil pipe layouts is obtained as 0.60, 0.80, and 0.78, respectively. The study reveals that the selection of pipe layout for the EATHE system mainly depends...

..., and angular airflow temperature distribution is used. The measurements covered balanced flow at a wide range of rotational speeds (0–24 rpm), regeneration temperatures ( 40 – 70 ° C ) , and airflow rates (160–530 kg/h). The influences of those parameters on the rotary regenerator effectiveness are presented...
