In this communication, an attempt has been made to obtain an analytical expression for the retention period of a given capacity biogas plant. It has been shown that the use of solar energy reduces the retention period. The ...

In this communication, an analysis of a double effect, active solar distillation unit has been presented by incorporating the effect of climatic and design parameters. Based on an energy balance in a quasi-steady condition, ...

In this paper, a study of convective mass transfer coefficient and rate of moisture removal from cabbage and peas for open sun drying and inside greenhouse drying has been performed as a function of climatic parameters. ...

We present performance studies of an earth air tunnel cum greenhouse technology in terms of instantaneous thermal efficiency. Analytical expressions have been obtained for heating/cooling conditions of a greenhouse. The ...

In the present paper, an attempt has been made to develop a computer model based on transient analysis of the greenhouse. The model predicts room air temperature, storage water temperature and the thermal energy storage ...

The thermal performance of a commercial solar hot water system for a constant delivery temperature is investigated as a function of various parameters, mass flow rate, heat exchanger parameters, collector parameters, number ...

This paper presents the thermal performance of a community type solar pressure cooker based on evacuated tube solar collector. The developed design of solar pressure cooker has separate parts for energy collection and ...

A mathematical model is devised to study the thermal behavior of a greenhouse while heating with a ground air collector (GAC). A computer program based on MatLab software has been used to predict the plant and room ...

This communication presents a dynamic model for determination of plant and the enclosed room air temperature in different zones of the micro-climate of a greenhouse. The numerical analysis and the experimental validation ...

In this communication, a new design of thin layer bed crop drying cum water heater has been proposed and analysed for making the whole system operate throughout the year. Energy balance equations for each component of the ...
