Diego‚ CA 92101‚ United States Received 28 September 2006 Available online 14 November 2007 Abstract Numerical simulations were performed to predict the film cooling effectiveness and the associated heat transfer coefficient in a 1-1/2 turbine stage. The leading edge of the rotor blade is film cooled with three rows of film cooling holes. The rotor tip leakage has been investigated for a clearance of 0.8% of blade span. Sliding grid is used for the rotor domain‚ and interface technique is employed

determine the volume flow rates of air to be pushed into the ducting system and the sizing of the major system components. Approaches to Temperature Control Temperature control in an air conditioning system is achieved by passing the air through the cooling or heating coil‚ which may use any of the following approaches: 1. Vary the temperature of air supplied to the space while keeping the airflow rate constant. This is the basic constant volume‚ variable temperature approach. 2. Vary the airflow

Optimization of Room Air Conditioning with Desiccant Wheel 1. Introduction Desiccant air conditioning technology is an emerging alternative air conditioning technology having many advantages over conventional VAC system. Desiccant cooling technology is free from CFCs‚ can be operated with low grade energy (heat energy) and capable of precise control of latent heat load of conditioned space. This eco friendly and energy saving method of air conditioning has drawn interest of many researchers over

system utilizing solar energy would generally be more efficient‚ cost wise‚ if it was used to provide both heating and cooling requirements in the building it serves. Various solar powered heating systems have been tested extensively‚ but solar powered air conditioning systems have received very little attention. Solar powered absorption cooling systems can serve both heating and cooling requirements in the building it serves. Many researchers have studied the solar absorption air conditioning system

In other words‚ the effect of cooling devices on soda cans. There will be four types of cooling devices used for the experiment. An ice-only bath with no water added‚ a freezer chamber‚ a refrigerator‚ and an ice-water bath with both ice and water added. This is the independent variables being tested‚ the four levels of cooling devices. The measuring
