Journal of Nanomaterials, Volume 2022, Issue 1, 2022., 2022 In order to maintain ideal working conditions by reducing heat from the system, a certain mechanism must be put into place. This research aims to investigate the effects of nanofluids on the performance of microchannel heating components used in computer cooling methods.

Modelling and Simulation in Engineering, Volume 2022, Issue 1, 2022., 2022 This research presents structural improvement of V‐shaped ribs for a tested square duct (TSD). The V‐shaped ribs, which are inserted at the middle of the TSD (called type A), and the V‐shaped ribs, which are placed on the opposite TSD walls (called type B), are modified to increase the structural stabilization. The effects of rib height to duct height,

Experimental and Numerical Analysis of the Flow Inside a Configuration Including an Axial Pump and a Tubular Exchanger [PDF]
, 2010 In centrifugal and axial pumps, the flow is characterized by a turbulent and complex behavior and also by physical mechanisms such as cavitation and pressure fluctuations that are mainly due to the strong interactions between the fixed and mobile parts ...

Flow Boiling in Minichannels [PDF]
, 2006 The use ofmini-channel heat exchangers (hydraulic diameter about 1 mm) in compact heat exchangers improves heat transfer coefficients, and thermal efficiency while requiring a lower fluid mass. They are widely used in condensers for automobile air-conditioning and are now being used in evaporators, as well as in other applications such as domestic air ...

Experimental study of blade rigidity effects on the global and the local performances of a thick blades axial-flow fan [PDF]
, 2010 An experimental investigation on the aerodynamic performances of thick blades axial-flow fans was carried out in this study. Two fans are considered, the first one is rotomoulded (in plastic) and the second one is milled (in aluminium). Both have exactly
