Abstract
The idea of thermal-dependent conductivity in transportation of heat has essential significance in ample industrial utilizations. The aspect of heat transportation in furnaces, fibrous, boilers, porous burners, foam insulations, etc. are instances of conduction aspect where temperature differ, and for this reason, alteration in conductivity is extremely higher. Some convected heat transportation processes encompass the thermal-dependent conductivity concept that can be scrutinized in chilling of electronic mechanism structural design along with heat exchangers. Taking into consideration the above-mentioned practicality of thermal-dependent conductivity, we analyzed buoyancy-driven stagnant-point flow subjected to heat sink and heat source. Cattaneo–Christov model which modify the traditional energy expression (i.e., energy expression obtained due to Fourier expression) is considered for modeling. The mathematical systems are simplified via application of boundary-layer theory. These systems are transfigured into dimensionless ODEs by utilizing similarity approach. The modeled dimensionless systems are evaluated employing homotopy procedure. Besides, novel characteristics of non-dimensional factors are inspected via pictorial outcomes.
