Single and Double Drop Impingement on a Heated Plate CFD and Experimental Investigation
نویسندگان
چکیده
A drop impingement on a hot surface is known as an effective way for heat removal. The present work uses VOF (volume of fluid) model to simulate the flow behavior and temperature distribution 50 °C heated plate while relatively cold water impinging. at zone used examine transient transfer coefficients using single double drops conditions. spreading factor tested in both cases. test rig built verify balance method introduced find experimental heated. CFD solution its results gives good agreement previous results. condition show high tendency rebound splash leaving central without coverage which causes burn out case fluxes. symmetrical lower value with non-uniform unsymmetrical specially bigger distances. average low error only 5% when compared values.

Experimental Investigation of Flooding and Drop Size in a Kuhni Extraction Column
In this research, Sauter-mean drop diameters and the flooding behavior have been investigated experimentally in a pilot scale Kühni extraction column. The experiments were carried out in the absence of mass transfer for two different standard chemical systems. In the experiments operating parameters including agitation speed, flow rate of both liquid phases and interfacial tension have been stu...
متن کاملExperimental investigation on the heat transfer performance and pressure drop characteristics of γ-Al2O3/water nanofluid in a double tube counter flow heat exchanger
In this paper, overall heat transfer coefficient and friction factor of water based γ-Al2O3 nanofluid in a double tube counter flow heat exchanger have been measured experimentally under turbulent flow condition. For better dispersion of γ-Al2O3 nanoparticles in distilled water, magnetic stirrer and ultrasonic vibrator (with a power of 240 kW and frequency of 35 kHz) were implemented. The stabi...
متن کاملShape optimization of impingement and film cooling holes on a flat plate using a feedforward ANN and GA
Numerical simulations of a three-dimensional model of impingement and film cooling on a flat plate are presented and validated with the available experimental data. Four different turbulence models were utilized for simulation, in which SST had the highest precision, resulting in less than 4% maximum error in temperature estimation. A simplified geometry with periodic boundary conditions is de...
