HEAT TRANSFERCHARACTERISTICS OF A SELF ASPIRATING POROUS RADIANT BURNER FUELE...BIBHUTI BHUSAN SAMANTARAY
This work presents the heat transfer characteristics of a self-aspirating porous radiant burner (SAPRB) that operates on the basis of an effective energy conversion method between flowing gas enthalpy and thermal radiation. The temperature field at various flame zones was measured experimentally by the help of both FLUKE IR camera and K-type thermocouples. The experimental setup consisted of a two layered domestic cooking burner, a flexible test stand attached with six K-type thermocouples at different positions, IR camera, LPG setup and a hot wire anemometer. The two layered SAPRB consisted of a combustion zone and a preheating zone. Combustion zone was formed with high porosity, highly radiating porous matrix, and the preheating zone consisted of low porosity matrix. Time dependent temperature history from thermocouples at various flame zones were acquired by using a data acquisition system and the temperature profiles were analyzed in the ZAILA application software environments.In the other hand the IR graphs were captured by FLUKE IR camera and the thermographs were analyzed in the SMARTView software environments. The experimental results revealed that the homogeneous porous media, in addition to its convective heat exchange with the gas, might absorb, emit, and scatter thermal radiation. The maximum heat transfer coefficient h, of the PRB was 40 w/m2k. The rate of heat transfer was more at the center of the burner where a combined effect of both convection & radiation might be realized.
Fischer-Tropsch fuels based on biomass and coal with carbon capture and storage could play a significant role in forming a low carbon transportation system. Coal and solar energy can power such a system allowing more of the carbon to be be integrated into the biofuels.

Effect of controlling parameters on heat transfer during spray impingement co...BIBHUTI BHUSAN SAMANTARAY
The heat transfer characteristics of air-water spray impingement cooling of stationary steel plate was experimentally investigated. Experiments were conducted on an electrically heated flat stationary steel plate of dimension 120 mm x 120 mm x 4 mm. The controlling parameters taken during the experiments were air-water pressures, water flow rate, nozzle tip to target distance and mass impingement density. The effects of the controlling parameters on the cooling rates were critically examined during spray impingement cooling. Air assisted DM water was used as the quenchant media in the work. The cooling rates were calculated from the time dependent temperature profiles were recorded by NI-cRIO DAS at the desired locations of the bottom surface of the plate embedded with K-type thermocouples. By using MS-EXCEL the effects of these cooling rate parameters were analysed The results obtained in the study confirmed the higher efficiency of the spray cooling system and the cooling strategy was found advantageous over the conventional cooling methods in the present steel industries.
