Experimental investigation of film cooling from two staggered rows holes,backward and forward; of opposite injection angles has been done. The forward holes row was embedded in arc trench. The aim of using arc trench is to enhance the poor mechanical properties of that in rectangular trench. The results of film cooling performance are given here in a form of adiabatic cooling film effectiveness and heat
transfer coefficients. In the tests test warm air is blown through tunnel, and cold air through the plenum chamber. When the warm air flowed through the test section it heated the model downstream. Infrared camera is used to measure the model surface temperatures. The comparison with the same holes arrangements and same holes and trench dimensions between existing rectangular trench results and present arc trenched
showed that the film cooling thermal performance for both cases are approximately very close with slight differences, these differences are more or less according to the values of blowing ratios.

The study is perhaps the first to evaluate and establish the relationship between
Quality, benchmarking, Reliability and globalization in industrial engineering activity
in Emirates, where the study was conducted on international companies operating in
Dubai. The study seeks to understand the impact & effect of globalization on all the
various topic of industrial engineering that distinguish implementing quality
management program, reliability program and ISO certified and benchmarking
companies from none implemented benchmarking or quality, reliability, ISO program.
Also the study tries to evaluate the effect of these factors on the organizational
performance. The study found a number of significant relationships between the
reliability, and globalization in industrial engineering activity. It also found support for
the argument that high reliability, high quality and benchmarking practices will
improve industrial engineering and at the end result will improve overall organizational
performance in large, medium and small global businesses. Therefore the results
achieve the goals of industrial engineering to eliminate wastes of time, cost, materials,
energy, and other resources to increase profits.
