The most dominant impact of the radiative heat transfer on soot formation is visible at the crank angles, where peak temperatures occur. The performed parameter study of the piston and head wall emissivity values showed a reduction in mean in-cylinder pressure and NO mass fraction for a less ...
Conjugate heat transfer 3D numerical model has been developed and successfully carried out. Rectangular winglets were set in pairs, with downstream orientation. The effects of impact angles of 5°, 10° and 20° as well as winglet height were examined through Nu number and j/f factor. Reynolds...
This research studies a three-dimensional fluid flow, and heat transfer in the heat sink numerically using air as a coolant. The numerical effects of the number of fins and their thickness on the performance of the heat sink are investigated using Ansys
The CH4/H2transportation problem model is general enough to consider various equipment operating modes. As mentioned above, this study examines the impact of CH4/H2mixtures in the operation of a compressor station and centrifugal blowers on CO2emissions. The pressure drop in the gas pipeline is an...
The impact of heat source Hs on concentration and temperature profiles is shown in Fig. 10a,b. The temperature profile decrements and the mass transfer increments and at the same time becomes linear at the augmenting value of the heat source Hs. Due to the domination of the heat absorption ...
