Use of solar energy for drying crop results in saving of conventional fuels and also offers advantages of less pollution and reduced dependence on the unreliable supply of conventional fuels. Forced convection solar dryers usually lead to a faster drying rate for the higher air flow rates and better control of air temperature is possible to obtain a better quality of the dehydrated product. A solar assisted forced convection dryer was developed and fabricated to study the effect of air flow rate and air temperature on the energy requirement for the dehydration of aonla. It has mainly consisted of a finned type - corrugated flat plate solar air heater, solar air heater outlet trapezoid, a centrifugal blower, auxiliary heating chamber, drying chamber, plenum chamber, drying chamber outlet trapezoid, temperature control unit, and flow measuring unit. Thermal performance of the developed solar air heater was determined at different airflow rates. Developed model is useful for scientific community.

Regenerative machines are those machines that can allow high heads at small flow rates and performance curves with very stable features. Unfortunately, the efficiency of regenerative blowers are not high, it is usually less than 50 %, thus this book aims to study the effect of inlet blade angle and blades number for improving efficiency by minimizing the losses as much as possible. An incidence loss is one of these losses that appears usually at the blade inlet regions. The increase of angle of attack (AOA) leads to the increase of the incidence loss (Shock loss). Since decreasing the effect of the shock losses and vortices could be obtained by changing the inlet blade angle and the blade numbers, the present work focuses on the study of the effect of inlet blade angles of (90 , 115 , 125 and 135 ), and blades numbers of (21, 31, 41 and 51) on the performance of regenerative blower at different rotational speeds of (1000, 2000, and 3000 rpm). The investigations are carried out analytically using two different 1-D models, experimentally, and numerically by the CFD.

When jockey Martin Stukely dies following a fall at Cheltenham, his friend Gerard Logan becomes embroiled in a perilous search for a stolen videotape.Logan, half artist, half artisan, is a glass blower on the verge of widespread acclaim for the originality and ingenuity of his work. Long accustomed to the frightful dangers inherent in molten glass and in maintaining a glass-making furnace at never less than eighteen hundred degrees Fahrenheit, Logan is suddenly faced with a series of unexpected and terrifying new threats to his business, his courage and his life.Believing the missing video tape to hold some sort of key to a priceless treasure, and wrongly convinced that Logan knows where to find it, a group of villains sets out to force from him the information he doesn't have. Narrowly escaping these attacks, Logan reckons that to survive he must himself find out the truth. The journey is thorny, and the final race to the tape throws more hurdles and more hazards in Logan's way than his dead jockey friend could ever have imagined.Glass shatters. Logan doesn't . . . but it's a close run thing.
