This webinar present a rapid and efficient design and optimization process for axial contra-rotating fans. The speakers - Prof. Mehrdad Zangeneh, Saurabh Gupta and Tobis Sieger - present application of TURBOdesign tools for the preliminary multi-blade row design of the axial fan where the rpm and pressure rise repartition of the different stages are varied. The results of the preliminary design work are shown to be in excellent agreement with 3D CFD validating the overall design process and solution.
