Design and Characterizations of Solar Steam Engine
In this paper a conceptual design of solar steam dish concentrated ( 2 m ) area was used .With cylindrical receiver as a solar boiler and two axis tracking system .the experimental were conductance from 80-150 °C under a mean solar flux of (250 -780 W/m) concentration product analysis of this innovative solar boiler applied drive to steam engine. We have found that overall efficiency of the conversion from direct solar irradiation energy to
Fabricated of Vertical Axis wind turbine (VAWT) and study the parameter
transmission lines and high prices of conventional fuel due to high pollution. A vertical system is used which depends on wind energy used to rotate a vertical turbine. The system is manufactured from local materials and tested. and study the number of blades with the other characterization of system we found, increasing the torque with increasing the blade of turbine, and increasing the power coefficient with increasing the tip speed ratio and low bitz limit.
Experiments on vapour jet refrigeration system suitable for solar energy applications
Experiments are carried out on a R11 vapour jet refrigeration system (VJRS) to study the influence of ejector configuration and operating conditions on the performance. Eight ejector configurations, formed out of five nozzles and seven diffusers are investigated. The influence of boiler temperature, which represents the solar energy collection temperature, and that of evaporating temperature, which denotes the cooling load temperature, are studied. Overall COPs in the range of 0.08-0.33 and evaporating temperatures in the range of −3–18°C are obtained for boiler temperatures from 75 to 85°C. Ejector configuration has significant influence in deciding the operating range.
