SOLAR DRYING OF YAM-FLOUR PELLETS.

Research output: Contribution to journalArticlepeer-review

Abstract

An experimental investigation of the heat/mass transfer characteristics of a turbulent impinging jet in cross flow in a model of a chamber used for solar drying of yam flour pellets is presented. The variables studied were the nozzle inclination alpha , and the jet-to-cross flow velocity ratio, M. These parameters were varied from 30 degree to 135 degree and from 5. 0 to 20. 9 respectively. Superimposing a cross flow onto the jet reduced the heat transfer coefficients. At low cross flows, inclining the nozzle further reduced the heat transfer coefficients. However, at higher cross flows, inclining the nozzle could be beneficial. The thin film napthalene sublimation technique was employed for the mass transfer measurements.
