  In my thesis i went through optimization of different compressor blades to find best profile to cut a step on it then i tried different modifications for the step on the blade after all numerical simulations and optimizations in the second phase of my project i made a model out of the resulted profile to be tested in cascade test cell for this purpose i had to prepare the wind tunnel and test section for testing as it was the first time for this facility to be used. i did leakage treatment for the wind tunnel then various tests were done to identify frequencies in which resonance happened afterwards tests were done in order to validate the flow entering the test section in terms of uniformity and turbulence then it was needed for accurate testing to control the wind tunnel fan automatically so i went to the invertors manufacturer company and learned about how to implement computer control for the invertors. then i had to learn about pressure sensors and their calibration and numerous tests were done for calibration purposes.afterwards the test section had to be modified provide range of motion required for adjusting angles of attack needed. the next step was redesigning the probe configuration on the section as it was not used before.finally i went through cascade testing of my designed stepped airfoils which exhibited better performance than ordinary airfoils used in compressor blades. نمایش موارد کمتر design, simulation and optimization of compressor blades.designing and making test prototypes to be used in cascade test rig( 3D printing, surfacetreatment, measurement holes and pipes)installation of cascade test section and conducting tests.implementation of communication system to control cascade test cell fan.training trainees on cascade test cell operation.construction of flow visualization assembly and conducting tests (laser installation, making lasersheet, design and construction of smoke generator).design and making probes of desired size for measuring static and total pressure.cooperation in designing and making computer controlled throttle for tandem compressor test rig.cooperation in steady and transient tests done on tandem compressor test rig to obtain stageperformance.doing flow visualization to demonstrate surge behavior of a tandem compressor stage.cooperation in construction and installation of industrial fan test cell. نمایش موارد کمتر
