Some modelling results from my PhD work

(full copy available from Cambridge University Library)

These modelling results show the use of code (simultaneous heat and mass transfer with a volumetric heat source) that the author developed to model both conventional (Heat Pump provided hot air) and in combination (including pulsed RF examples) with RF for drying of various homogeneous materials such as clay aggregate, crushed brick and green-bricks, whilst working at the Electricity Utilisation Group (EUG), Cambridge.  Click on the small image to view full size.

	Example showing how the Smith chart can be used to dynamically  tune an RF power source (free running or crystal driven) to a coupled load for optimum power transfer.
Modelling results showing excellent agreement with the experimental results.
	The layering effect produced as a heated-air drying front progresses vertically up-through a bed of material.
Example of predictive modelling results for both moisture and temperature for heat pump in combination with RF drying of crushed brick.
	Predictive modelling validated experimentally, showing how the model developed can be used in a "what-if-scenario" to model the effects of differing levels of hybrid RF and Heat pump drying.
