Thermal conductivity, FEM (Finite Element Modelling), ceramic wool, rock-wool, composite.Abstract
Astudy is carried out for determining the effective thermal conductivity of a composite of ceramic fibre and rock-wool. Literature review reveals that the rock-wool result in reduction of thermal conductivity of the composite for possible industrial applications in geyser, insulated wall construction, food container, thermal flask, electric geysers, heating furnace, aerospace structures (to withstand high temperature due to viscosity drag) etc.A composite of ceramic fibre and rock-wool is developed using hand lay-up technique with binder. For the purpose of measurement of thermal conductivity values, Unitherm thermal conductivity measuring instrument is used according to the ASTM standard E-1530. 3D models are made to simulate the composite materials for various concentrations ranging from about 6 to 30 vol. % of rock wool. Determination of the thermal conductivity of ceramic fibre and rock-wool composite is done by using FEM and verified by experimentation. From simulation we find that a 3D model of composite gives a thermal conductivity of 0.5 W/m-K with 8% filler concentration and furnace temperature being 600o C. When the furnace temperature is kept 600° C the thermal conductivity reduces to 0.44 W/m-K with 14% filler concentration.
