renewable solar energy. From the results of project calculations a truthful estimate was made to prototype the most effective geometries of the distiller and trough concentration system‚ one that will maximize evaporation/condensation and re capture waste heat to minimize thermal losses. To achieve this goal‚ a system was designed incorporating a parabolic solar trough coupled with a custom designed distillation device. The incoming solar radiation from the sun is focused and concentrated onto a receiver

The elements influencing the drying method of rotary dryers may be classified into two styles: a single may be the variables caused through the rotary dryer itself‚ which includes the lifting board‚ the rotation velocity with the drying machine plus the heat insulation of the dryer cylinder and also the other 1 is the drying

through 3 consider conduction heat transfer in a stationary medium. Energy transport within the material of interest occurs entirely by conduction and is governed by Fourier’s law. Convection is considered only as a boundary condition for the relatively simple ordinary or partial differential equations that govern conduction problems. Convection is the transfer of energy in a moving medium‚ most often a liquid or gas flowing through a duct or over an object. The transfer of energy in a flowing fluid is
