Abstract

The objective of present study is to evaluate the effect of the length and location of segmental heating of inner radius of annular cylinder containing porous medium between inner and outer radii. The fluid and solid matrix of porous medium are assumed to have temperature discrepancy subjected to isothermal heating of heater. The fluid is assumed to follow Darcy law and two separate equations are considered for energy transport to account for the thermal non-equilibrium condition. The boundary conditions are such that fluid and solid phase have different temperatures at the hot wall. The study is conducted for different lengths of heater corresponding to the 20%, 35% and 50% of the total height of the cylinder. The location of the heater is varied to three positions i.e. bottom section, mid-section and top of the cylinder.
