Comparative study on two novel intermediate temperature CPC solar collectors with the U-shape evacuated tubular absorber

TL;DR: In this article, two truncated compound parabolic concentrating (CPC) solar collectors, which combine the external CPC and the U-shape evacuated tube together, have been developed and tested.
Journal ArticleDOI

Off-design optimisation of organic Rankine cycle (ORC) engines with piston expanders for medium-scale combined heat and power applications

TL;DR: In this article, an off-design optimisation tool is developed and used to predict the impact of varying heat-source conditions on ORC operation, which can be used to identify optimum performance under real operating conditions.
Journal ArticleDOI

Simultaneous determination of thermal conductivity and thermal diffusivity of food and agricultural materials using a transient plane-source method.

TL;DR: In this article, a transient plane-source method was developed to measure thermal conductivity and thermal diffusivity in a variety of materials, but its application in foods has not been documented.
Journal ArticleDOI

Experimental investigation of a thermosyphon based heat exchanger used in energy efficient air handling units

TL;DR: In this article, an experimental investigation of the thermal performance of an angled air-air heat pipe heat exchanger, which utilizes thermosyphon technology, is presented, and the results also allow the prediction of effectiveness variation with the variation of the operating temperature.
Journal ArticleDOI

A physical model of switching dynamics in tantalum oxide memristive devices

TL;DR: In this paper, the authors present a resistive switching model for TaOx memristors, which demonstrates that the radius of a tantalum rich conducting filament is the state variable controlling resistance.
