In this present paper, gap-27 heat influx on the multiple tubes in the cavity receiver was assumed to be constant. But during different time of the day, the radiation may vary in parallel absorber tubes. Variation of radiation heat flux on all tubes and analysing the thermal–hydraulic will turn the problem into a purely transient one. With different flow rates in different tubes along with different heat fluxes makes the problem little complicated. One has to start with optical analysis and move accordingly for different flux considerations on different tubes. These are scope for the further study of this solar thermal application.

There has been growing interest in wind energy in the past two decades because it is a potential source of electricity associated with minimal environmental impact. Commensurate with advancements in this industry, wind turbines are now available, at low cost and over large scales, which can produce considerable amounts of power . Currently, approximately 6% of total electrical consumption in the US and Europe is provided by wind, although the wind industry intends to produce more than 20% of the electrical energy in these countries within the next two decades . To achieve this goal, a number of improvements are required in the areas of aerodynamic, electronic and control design.
