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 ...

Expressions for water and glass temperatures, hourly yield and instantaneous efficiency for both passive and active solar distillation systems have been derived. The analysis is based on the basic energy balance for both ...

A mathematical model through flowing water film on shade cloth, stretched over the roofs and south wall of an even span greenhouse has been developed to study the effectiveness of cooling in greenhouse. The model was ...

The present study is concerned with the analysis of solar desalination system combined with a greenhouse for both composite and warm humid climate of India. Analytical expressions for water temperature, greenhouse room air ...

This paper presents the annual performance of an active solar still. Analytical expressions for water and glass cover temperatures and yield have been derived in terms of design and climatic parameters. Numerical computations ...

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. ...

A thermal model has been developed for the heating of a greenhouse by using inner thermal curtain and natural flow of geothermal warm water through the polyethylene tube laid on its floor. The calculations were done for a ...

A simplified analytical model is developed to study the year round effectiveness of a recirculation type earth air heat exchanger coupled with a greenhouse located in IIT Delhi, India. The performance of the system was ...

This communication deals with the development of a mathematical model for experimental validation of the thermal behavior in the greenhouse after evaporative cooling. Extensive experiments have been performed during July ...

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 ...
