JME_V2_N2_RP7 Dhananjay R. Mishra Anil Kumar Tiwari Journal on Mechanical Engineering 2249 - 0744 2 2 41 45 Thermal Simulation, Shape Factor, Sunken Effect Partially and fully sunken effect on slab-on- grade structures are reported, using silica sand as a simulating media in thermal simulation method for estimating the ground losses. The method has been used to determine the shape factor ; which can be used to evaluate the heat loss to the ground for slab-on- grade. The accuracy of the method has been evaluated by comparing the experimental result obtained for a sphere with the corresponding analytical results.
