Abstract
The scope of project work comprises measurement of physical, micro structural, mechanical, thermal properties and heat transfer simulation were carried out on assynthesized porous silica ceramics by direct foam method. In this investigation porous ceramics showed 86% porosity. The density and shrinkages were calculated from dimensional measurement method. The micro structural characterization was performed using scanning electron microscope (SEM) to evaluate the pore sizes within the sample. The mechanical strength for porous ceramics was evaluated by compression test using universal testing machine (UTM). For examining the thermal property of the porous samples, a thermal conductivity set up has been designed and fabricated (in-house) for measuring the thermal conductivity using heat transfer approach. The modeling of porous ceramic sample was done using Finite Element Analysis (FEA), to observe the temperature and heat flux distribution across the thickness.
