in this numerical study the the heat transfer and laminar nanofluid flow in the three-dimensional microchannels with triangular cross-section is simulated. for increase the heat transfer from the walls of the channel, semiattached & offset mid- truncated rib,s placed in the canal, and the tooth geometry and the impact is studied. in this study, the water is base fluid, and the influence of the ...

introduction: frying phenomena occur during the immersion of the product in oil at a temperature of 150–200 ºc, where a simultaneous heat and mass transfer take place. this is the most popular thermal processes of potato cooking. this fast drying is critical to improve the mechanical and structural properties of the final product. these conditions lead to high heat transfer rates, rapid cooking...

Amid all convective heat transfer augmentation methods employing single phase, jet impingement delivers significantly higher coefficient of local transfer. The arrangement leading to nine jets in square array has been used cool a plate maintained at constant flux. Numerical study carried out using RANS-based turbulence modeling commercial CFD Fluent software. turbulent models for the are three ...

Turbine inlet temperature has continuously increased to improve gas turbine performance during the past few decades. Although internal convection cooling and traditional film have contributed significantly current achievement, advanced schemes are needed minimize coolant consumption maximize efficiency for future turbines. This paper conducts a comprehensive review of effusive blades. First, ba...

Using of nanofluids and ducts with corrugated walls are both supposed to enhance heat transfer, by increasing the heat transfer fluid conductivity and the heat transfer area respectively. Use of a diverging duct with a jet at inlet section may further increase heat transfer by creating recirculation zones inside the duct. In this work two-dimensional incompressible laminar flow of a nanofluid e...
