As technology advances, so must our methods. One of the most important aspects when working with physical instruments is to maintain heat flow in the desired direction. The transient plane source is a single unit that produces heat while doubling as a temperature sensor, so it is an excellent way to control and monitor the movement of heat without loss to the environment. The sensors for the TPS model are ...
The Transient Plane Source (TPS) Technique measures the thermal conductivity, thermal diffusivity, and specific heat of solids and liquids. An electrically conducting double spiral nickel sensor pulses a current through a sample which increases its temperature, while simultaneously recording the length of time it took for the sample to heat up. This study, researchers tested the thermal properties of various materials and determined that anisotropy must be considered when these ...
The thermal conductivity and thermal diffusivity of SRP (sisal-reinforced polyethylene), GRP (glass-reinforced polyethylene), and GSRP (sisal/glass hybrid fibre-reinforced polyethylene) were tested from 120 to 350K. Results showed variances in thermal conductivity values with varying temperatures in materials containing different orientations of sisal fibres. Due to the anisotropic nature of the SRP fibre, there is a difference in the thermal conductivity readings from the parallel to the perpendicular direction. The GRP ...
