Abstract
This study investigates a measurement method of thermal diffusivity for samples with arbitrary geometries and unknown material properties. The aim is to curve fit the thermal diffusivity with the use of a numerical simulation and transient temperature measurement inside the object of interest. This approach is designed to assess bulk material properties of an object that has a composite material structure such as underground soil. The method creates the boundary conditions necessary to apply analytical theory found in the literature. It was found that measurements best correlated with theory and simulation at positions between the center and surface of an object.
Highlights
The validation of the COMSOL model using the analytical theory for a sphere proved a success
The legs are sinks to heat augmenting the temperature sivity via a transient temperature measurement inside an object immersed in a moving evolution with surfaces the assumption of The constant heat transfer. material was fluid and comparison withoutside a numerical simulation
The results of this study have found a viable method determining thermal to sivity take the related theory and results to support the construction of a test rig capable of via a transient temperature measurement inside an object immersed in a moving measuring cylindrical geometry
