The radiant time series method is a new method for performing design cooling load calculations, derived from the heat balance method. It effectively replaces all other simplified (non-heat-balance) methods such as the cool#zg load temperature difference~solar cooling load~cooling load factor method (CLTD/SCL/CLF), the total equivalent temperature difference~time averaging method (TETD/TA), and ...

Studies at the University of Southern California have shown that an unconventional solid-state device, the Knudsen Compressor, can be operated as a micro-scale pump or compressor. The critical components of Knudsen Compressors are gas transport membranes, which can be formed from porous materials or densely packed parallel arrays of channels. An applied temperature gradient across a transport m...

In the present paper, we have presented a Maxwellian boundary-type solution for total internal reflection with unbounded incident waves at an interface between two nonabsorbing media, in which the instantaneous, time varying, and time averaged radiant fluxes have been determined at all points in the two media. Solutions for the s and p polarizations were found for which the instantaneous tangen...

This paper discusses optimal control strategies for switching between different burner modes in a novel compact marine boiler design. The ideal behaviour is defined in a performance index the minimisation of which defines an ideal trade-off between deviations in boiler pressure and water level from their respective setpoints and the cost of burner switches and variation of continuous input flow...

We study the optimization of the spatial distribution of fuel injection rates in a gas turbine burner. An automated procedure is implemented for the optimization. The procedure entails an evolutionary optimization algorithm and an automated interface for the modification of the parameters in the experimental setup for the fuel injection and for the post-processing. The evolutionary algorithm is...
