Oscillating flows have fundamental effects on the heat and mass transfer of Stirling engines and gas springs. A complex velocity model was proposed to describe the fully-developed laminar oscillating flow through introducing complex functions and simplified control equations. The maximum...

This paper attempts to categorize solar stills into six sorts based on the design guidelines used in each device. The properties of these design guidelines are detailed and evaluated from the angle of enhancing the productivity of solar stills. Preferred design guidelines are recommended for...

A Lambertian CCD-camera method is convenient to measure concentrating radiation fluxes, where a crucial factor, a calibration factor, always varies with spectra and brings errors. In this paper, a new calibration method is proposed based on spectral normalization calculation and tries to reduce...

A solid-particle solar receiver was proposed to convert concentrated solar beams into heat for high-temperature thermal storage in a two-stage dish system. Spherical Xe-arc lamps were used to simulate a solar light source. The performances of this receiver under a Xe-arc lamp array system were...
