Laser Flash Analyzer for Measurement of Thermal Conductivity and Diffusivity of Liquids and Solids

导热系数是影响各种材料性能的重要参数。激光闪光分析仪可以为我们提供材料在广泛温度范围内的热扩散率和导电率的准确数据。目前，加拿大的大学还没有类似的设备。申请人概述的几个不同研究领域都需要所要求的设备；这包括创新的安全核燃料、热应力对锆合金和管线钢失效的影响、纳米材料的热性能、化学反应研究中使用的固体催化剂、光导体合金的热导率、热防护服和消费品、用于液体-空气能量交换器的膜的热导率、用于建筑围护结构的材料的热导率、土壤的热导率和热扩散率以及新型合成材料在高温下的抗热震性研究。目前，已确定萨斯喀彻温省大学6名教授的13个研究项目。这种设备对于申请者实现他们目前和计划中的研究目标是必不可少的。这里需要指出的是，目前新型核燃料的研究对加拿大核能的发展至关重要，激光闪光分析仪也将用于验证我们对添加UO2和PuO2的氧化钍的热导率的从头计算。这项研究得到了参与加拿大钍核反应堆设计的坎杜工业公司的支持。这样的反应堆将是安全可靠的热能和电能来源。

Thermal conductivity is an important parameter influencing the performance of variety of materials. Laser Flash Analyzer can provide us with the accurate data on thermal diffusivity and conductivity of materials in a wide range of temperatures. At present, similar equipment is not available at the universities in Canada. The requested equipment is necessary in several different areas of the research outlined by the applicants; this includes innovative safe nuclear fuels, thermal stress effect on the failure of Zircaloys and pipeline steels, the thermal properties of nanomaterials, solid catalysts used in the chemical reaction studies, thermal conductivity of photoconductor alloys, thermal protective clothing and consumer products, the thermal conductivity of membranes used in liquid-to-air energy exchangers, the thermal conductivity of materials used in building envelopes, thermal conductivity and thermal diffusivity of the soils and the studies of thermal shock resistance of the novel synthesized materials at high service temperatures. At present, 13 research programs of 6 professors at the University of Saskatchewan were identified. This equipment will be essential for the applicants to realize objectives of their present and planned research. Here, it is necessary to point out that at present, the study of novel nuclear fuel is vital for the development of Canadian nuclear energy and the Laser Flash Analyzer will be also used to verify our ab initio calculations of thermal conductivity of thorium oxides with additives of UO2 and PuO2. This research is supported by Candu Industry Inc. that is involved in the design of Canadian thorium nuclear reactor. Such reactor will be safe and reliable source of thermal and electrical energy.
