RISPressure Drop and Thermal Performance of CuO/Ethylene Glycol (60%)- Water (40%) Nanofluid in Car Radiator
We investigated the role of nanofluid in a special car radiator and the effect of its different volume concentrations
on pressure drop and friction factor of fluid flow. A mixture of 60/40 ratio of ethylene glycol (EG) and distilled...
Experimental investigation of thermo-physical properties, convective heat transfer and pressure drop of functionalized graphene nanoplatelets aqueous nanofluid in a square heated pipe
Experimental investigation of thermo-physical properties, convective heat transfer and pressure drop of functionalized graphene nanoplatelets aqueous nanofluid in a square heated pipe
Effects of Friction Factor and Inlet Stagnation Conditions on the Self Condensation of Steam in a Supersonic Nozzle
this paper describes a theoretical study of the self-condensation of non-equilibrium wet steam during supersonic expansion in a de Laval nozle. Nucliation and droplet growth theories have been combined with the equations ...
Pressure drop and performance characteristics of water based Al2O3 and CuO nanofluids in a triangular duct
of adding nanoparticles to the base fluid on the
pressure drop and friction factor are investigated at different Reynolds numbers. The results
show that at a specified Reynolds number, using the nanofluids can lead to an increase in the...
A general optimized geometry of angled ribs for enhancing the thermo-hydraulic behavior of a solar air heater channel e A Taguchi approach
of heat transfer coefficient and minimization of friction factor. Maximization of thermal enhancement factor is taken as the criteria of optimization. At a constant flow Reynolds number of 10000, rib relative pitch (P/H), rib relative height (e/H), rib...
Synthesis of aspartic acid-treated multi-walled carbon nanotubes based water coolant and experimental investigation of thermal and hydrodynamic properties in circular tube
-functionalized MWNT with aspartic acid. The prepared nanofluids in three weight concentrations of 0.05, 0.1 and 0.2% are investigated in the flow rate range of 2.86 to 8.85 ml/s. Thermophysical properties, convective heat transfer coefficient, pressure drop, friction...
Unsteady natural gas flow within pipeline network, an analytical approach
absolute present derivation (AAPD) less than 0.7%. Finally the effect of a few parameters including: friction factor, natural gas composition and decreasing and increasing demand have been studied. Results show that Weymouth and AGA equation predict highest...
Performance intensification of turbulent flow through heat exchanger tube using double V-cut twisted tape inserts
This paper aims to present a numerical model for heat transfer intensification in a heat exchanger tube equipped with novel double V-cut twisted tape. The effects of different cut ratios (0.6 < b/c<1.8) on the turbulent ...
