The need for rational and overall water resources management has become, during the past decades, a problem ofmajor importance due to the rising water demands. In this paper atechnique is presented through which a management model that combines the useof two separate models, a flow simulation...

A computer-based numerical model has been developed utilising ray trace techniques, to simulate the optical characteristics of asymmetric inverted absorber line axis compound parabolic concentrating solar collectors (IACPCs). Cognisance is taken of the separate effects of the beam and diffuse...
