SIMPLE THERMAL WAVE METHOD FOR THE DETERMINATION OF LONGITUDINAL THERMAL DIFFUSIVITY OF SiC-BASED FIBER
نویسنده
چکیده
Silicon carbide fibres have proven to be an excellent reinforcement material in ceramics and other composites due to their high strength and stiffness and good thermomechanical stability. The thermal diffusivity/conductivity of SiC based fibres has been reported earlier [1]. The methods used so far for the fibres have been mainly indirect and based on using a composite of known composition and then applying a standard thermal conductivity measurement on that system. Fiber properties have further been obtained from an inversion calculation. Direct measurement data of fibre properties has not been available.

Development of a Moving Finite Element-Based Inverse Heat Conduction Method for Determination of Moving Surface Temperature
A moving finite element-based inverse method for determining the temperature on a moving surface is developed. The moving mesh is generated employing the transfinite mapping technique. The proposed algorithms are used in the estimation of surface temperature on a moving boundary with high velocity in the burning process of a homogenous low thermal diffusivity solid fuel.

We report the results of a thermal wave study on SiC/B4C composites of different B4C compositions. Thermal wave, generated subsequent to sample absorption of pulse laser, was observed by means of a wide-band infrared detector. The information content of the thermal wave is then analysed by using a least-squares method. Temperature decay time, as measured from thermal wave decay curve, varies wi...
