Energy, 1983
Abstract An air heater, in which the air first flows between metallic and cover plates and is then made to flow between two metallic plates in opposite direction, is discussed theoretically. The governing equations of the model are solved explicitly under suitable conditions.

Applied Thermal Engineering, 1996
In the present communication, efforts have been made to study the drying characteristics of coriander in a stationary 0.5 tonne/batch capacity deep-bed dryer coupled to a solar air heater and a rockbed storage unit to receive hot air during sunshine and off-sunshine hours, respectively.

Theory of baffled solar air heaters
Energy, 1992Abstract Considerable improvement in the collector efficiency of solar air heaters can be obtained if the fins in the collector have attached baffles to create air turbulence and an extended heat-transfer area. In this paper, energy balances in baffled solar air heaters have been developed and a theoretical equation for estimating the collector ...

Dynamic behaviour of baffled solar air heaters
Renewable Energy, 1998A mathematical model describes the dynamic thermal behaviour of a baffled solar air heater is presented. The transient behaviour of the heater results from sudden changes in the intensity of the incident solar radiation and the inlet fluid temperature.

Prediction of Solar Air Heater Thermal Performance
Transactions of the ASAE, 1985ABSTRACT THE prediction of steady state thermal performance of solar air heaters requires prediction of three parameters: the effective transmittance-absorptance product, the collector heat removal factor and the collector loss coefficient. Agreement between computed values and measured values of these parameters indicated that the first two parameters

Design Equations for Solar Air Heaters
Transactions of the ASAE, 1980ABSTRACT THE Hottel-Whillier-Bliss generalized performance equation is probably the best available mathematical description for the performance of a flat plate collector. The most useful form of this equation utilizes the collec-tor heat removal factor and the collector loss coefficient.

Solar air heater applications in India
Renewable Energy, 1999Abstract Solar air heaters of many types have been developed in India and their performance studied in detail. The application of these air heaters are limited to a few demonstration projects for food dehydration, and space heating. Some of these case studies are described in this paper.

Single Pass Solar Air Heater Without Absorber
2014The single pass solar air heater is constructed and tested for thermal efficiency at a geographic location of Cyprus in the city of Famagusta. The length and the width of the collector are 150 and 100 cm respectively. The distance between the cover glass, 0.4 cm in thickness, and the bottom of the collector, is 3 cm.

Thermal performance of solar air heaters—Experimental correlation
Solar Energy, 1995A mathematical model and a solution procedure for predicting the thermal performance of four types of single-pass flat-plate solar air collectors were presented in an earlier paper by Ong (1995). Instead of resorting to complicated algebraic manipulations to solve the energy equations a matrix-inversion technique was employed.

Efficiency of solar air heaters with baffles
Energy, 1991Abstract Considerable improvement in the collector efficiency of solar air heaters is obtained if the fins in the collector are provided with attached baffles to create air turbulence and an extended heat-transfer area. This procedure will increase the pressure drop for the air across the heater and thereby leads to some increase in the power ...
