A simplified approach for predicting temperature profile in steel members with locally damaged fire protection

The structural integrity of steel members is jeopardized when fire insulation is partially lost. This paper examined the thermal and mechanical properties of fire insulation under elevated temperatures to further understand thermal gradients and develop preventative safety measures. A thermal analyzer measured the thermal conductivity of the insulation material using the transient plane source (TPS) method. Results show that thermal conductivity increases with temperature because the spray-applied fire resistance materials ...

Thermal conductivity measurement

The transient technique is the commercial method used to test the thermal conductivity, thermal diffusivity, and specific heat of solids. With the instrument, a double spiral nickel sensor is sandwiched between two homogenous samples, and as the sensor pulses electrical currents through the sample, it simultaneously measures how long it takes for the temperature of the sample to increase. This method is typically used on glasses, insulating materials, and polymer ...

Study of coupled transient radiation-natural convection heat transfer across rectangular cavities in the vicinity of low emissivity thin films for innovative building envelope applications

As buildings are constructed, pores and cavities are formed within the building envelope and can cause issues with coupled transient radiation-natural convection heat transfer. This research aims to develop a model to minimize the empty space in the area lining the exterior and interior of the building (building envelope). As cavities and pores are present within the building envelope, issues of heat loss and high energy consumptions arise. An improved ...
