The article deals with spatial heat-stressed elements that influence the thermal properties of multilayered enclosing structures. Using the ANSYS finite element program, the effect of thermofiller location on heat transfer processes is studied nearby the heat-stressed elements. A quantitative assessment is given to thermal conditions of heat-stressed elements of enclosing structure under extreme heat exchange conditions. Specific conditions are created to raise the temperature nearby the heat-stressed elements and reduce their negative effect.

The passage of an ultrasonic wave through a mixture of polyborosiloxane and silicon carbide abrasive, when used in a honing process, causes heating due to the attenuation of the said wave. This is critical to the honing process since the temperature in the components being treated must be limited to about 70° C. A numerical model of the heat generation and transfer processes in the polishing medium is being formulated, which requires knowledge of the thermophysical properties of the mixture. This investigation concentrates on the experimental determination of thermal conductivity, specific heat capacity and surface heat transfer coefficient for various mixtures of polyborosiloxane and silicon carbide abrasive. Theoretical, semi-empirical and empirical models are derived for the variation of these thermal properties as functions of both material composition and temperature.

Important Design

It is known that heat-stressed elements greatly affect the thermal properties of walling and contribute to the heat losses of a building. Heat-stressed elements decrease the temperature on the inner walling surface adjacent to the external corners. In addition to increasing heat losses, heat-stressed elements increase the condensation on the inner walling surface leading to mold appearance. This is one of the reasons that shows that the modeling of heat-stressed elements is a very important design stage. The article discusses the effect from these elements on thermal properties of multilayer walling in the external corner of a building. Using the ANSYS software package, the influence of heat-stressed elements on the heat transfer processes is modeled in the external corner area. A quantitative assessment of the thermal state of typical walling fragments under extreme heat-transfer conditions is given. The obtained research results can be used to increase the temperature in the area of heat-stressed elements and reduce their negative impact.
