We show how the thermal losses within and outside a solar distillation unit vary with water depth in the basin of a passive solar still. The latent heat of vaporisation has been used for distillation under both passive and active modes of operation. The flow rate of the water mass over the glass...

This paper examines non-isothermal effects during carbon dioxide injection into a depleted gas reservoir for storage and EGR (enhanced gas recovery). We illustrate Joule–Thomson behavior with VHD (viscous heat dissipation) effects during reservoir repressurization. The equations of state for...

Wheat covers approximately 25% of the total global area devoted to by cereal crops. Wheat production needs to be augmented to meet the growing demand. The amount of wheat produced is a direct function of energy inputs. Wheat is produced using energy sources ranging from human and animal power to...

Thermochemical energy storage can play an important role in the establishment of a reliable renewable energy supply and can increase the efficiency of industrial processes. The application of directly permeated reactive beds leads to strongly coupled mass and heat transport processes that also...

We have studied an active solar distillation system during peak summer days. The system is made of fibre-reinforced plastic (FRP) and is coupled to a flat-plate collector (FPC). Performance of single and double-effect solar distillation, with and without water-flow over the glass cover, was...

We present an analysis of an indoor swimming-pool with solar collector panels. An analytical expression is derived for the system efficiency in terms of heat-exchanger and collector designs and climatic parameters.

We present an analytical model of a ground collector which uses thermal trap material instead of glazing on its top. The effects of different parameters e.g., the depth of the heat retrieval plane, thickness of the thermal trap material and the use of various materials such as concrete, sand and...

The design criteria for thermal heating of an active, fixed-dome type biogas plant are presented. The effects of the heat exchanger and collector panel have been incorporated in the thermal analysis. The thermal efficiency of the system can be optimised by increasing the flow rate of the working...

Open sun drying (OSD) is the most common method of crop drying in developing countries. Despite several disadvantages, it is widely practiced because it is a simple way of drying. Crop temperature, temperature around the crop, solair temperature, and rate of moisture evaporation are the...

We analyse the performance of a flat-plate collector with a constant rate of evaporation of flowing water between a glass cover and an absorbing plate. The effects of fluid-flow velocity, depth of fluid and length of the absorbing surface are discussed. We have allowed for periodic variation of...
