An Experimental Study of the Thermal Performance of Refractory Coatings Exposed to a Tokamak
نویسندگان
چکیده
A thermal diagnostic for evaluating the performance of refractory coatings under a variety of heat loads is demonstrated. Heat flow through refractory coatings of TiC exposed to the edge plasma of Microtor II was measured using coated copper samples instrumented with thermocouples. Using interior temperature data, the inverse heat conduction problem was solved numerically to obtain the surface temperature and heat flux during the plasma pulse (50-70 ms typical duration). Features in the thermal profiles could be resolved to within less than 10 ms.

FAILURE MECHANISMS OF REFRACTORY LININGS FOR NONFERROUS FLASH SMELTING FURNACES
Although the flash smelting technologies use different furnace designs, the refractory linings are exposed to very similar aggressive environments and, as a result, the corrosion analysis results on one type of furnace could be generally applied to other furnaces of similar high temperature processes. Particularities regarding the different chemistries of the pyrometallurgical process and opera...

This paper reports the thermal performance of a new cylindrical solar collector based on an experimental investigation with this difference that instead of the collector tube with absorbent coating, coil into a spiral copper tube is placed in the center of the collector. The spiral shape of the tube, heat transfer without disruption or increase the heat transfer area, is increasing. In this cas...
متن کاملExperimental study on thermal conductivity of polyurethane resin filled with modified nanoparticles
One of the ways to waste energy in buildings is wasting it from the walls. For this reason, insulating materials are used to prevent the loss of energy in buildings. Typically, common insulations are high thickness and thin coatings are used less. The purpose of this research is to introduce nanocomposite thin polymer coatings and its effect on thermal conductivity. For achieving this, chemical...
متن کاملExperimental and Numerical Study of Residual Stress in the WC-12Co HVOF Sprayed Coatings
Thermally sprayed coatings are intrinsically associated with residual stresses in the deposits. These stresses are varied in nature and magnitude, and have a pronounced effect on the mechanical behavior of the system. In the current study, WC-12Co coatings were deposited using HVOF thermal spraying. The sin2ψ method was used to evaluate the through thickness residual stress by means ...
