Ph.D. research
details
A theoretical model was developed for heat transfer and condensation inside a typical proposed exhaust heat exchanger passage of a fuel cell condenser in the presence of a non-condensing gas. The predicted flow regime is annular. The model applies to any vapour-gas combination. For a prescribed composition, temperature, pressure and flow rate of the gas mixture at inlet and prescribed wall temperature distribution along the tube, the model predicts the local heat-transfer and condensation rates and the local bulk vapour composition, temperature and pressure. The model has been validated using experimental data for air-steam mixtures over a wide range of relevant variables (steam-air inlet composition, pressure, temperature and flowrate; coolant inlet temperature and flowrate). The model can be used in conjunction with a standard approach for the outside heat transfer to give complete model for an air-cooled heat exchanger passage.
Summary of work done
When using water as coolant (for convenience) to simulate the airside resistance in the actual fuel cell condenser application, it was necessary to operate at low velocity and hence low Reynolds number. A laminar flow coolant mixer was designed, fabricated and tested for this purpose.
A test rig was designed and all major components manufactured and assembled.
An outline scheme was drawn up for modelling the in-tube heat and mass transfer processes and a database of relevant thermo-physical properties assembled. Property equations for the vapour-gas mixture were verified and subsequently the used to develop a full.
Thermocouples, used in the main rig, were calibrated against a platinum resistance thermometer having high precision (accuracy
better than 0.05 K).
3
Commission runs on the main test rig were completed and experimental runs using air-steam mixtures were carried out followed by data analysis and reduction. The same was used to validate the model and good agreement was found.
