Evaluation of Mass Transfer Coefficient during Scrap Melting

چکیده
Mass transfer is a critical scrap melting step. Herein, mass coefficients (k) during were calculated using laboratory-scale experiments. Correlation analysis and the entropy weight method used to determine effect of variables on k. The evaluation model under natural forced convection was established. It consistent with experimental results. Under convection, at 1573 1673 K, when rotation speed increased from 141 423 r/min, k 7.50 × 10−5 1.54 10−4 m/s 8.42 1.72 m/s, respectively. Furthermore, as bath temperature 1723 value stationary specimen 3.14 5.31 indicated that effects decreased follows: molten pool stirring rate > type. Moreover, explicit functional relationships between factors affecting conditions established, results data. Our can be quantitative

Evaluation of convective mass transfer coefficient during drying of jaggery
In this paper an attempt is made to evaluate the convective mass transfer coefficient during drying of jaggery in a controlled environment. In this method, different masses of jaggery were used. The jaggery was dried in the roof type even span greenhouse with a floor area of 1.2x0.8 m in natural and forced convection mode at atmospheric pressure till it attained almost no variation in mass. The...

Experimental measurement of heat transfer coefficient and mass of deposited CaSO4 in subcooled flow boiling condition
Fouling is a common, fundamental and costly problem in heat transfer systems, which reduces thermal efficiency of equipment, increases the energy loss and causes strong damage to the heat transfer equipment in various industries. The main causes of fouling on the heat transfer surfaces are salts with inverse temperature-solubility in the fluid which calcium sulfate is one of the most important ...

Investigation of Mass Transfer Coefficient under Jetting Conditions in a Liquid-Liquid Extraction System
In this research mass transfer coefficient under jetting regime in different directions (from dispersed to continuous and continuous to dispersed phase) has been studied using an experimental setup. n-Butanol-succinic acid-water with low interfacial tension has been selected as experimental chemical system. The effects of various parameters such as jet velocity, nozzle diameter and the heig...
