Abstract

UNDERGRADUATE RESEARCH ON CONCEPTUAL DESIGN OF A WIND TUNNEL FOR INSTRUCTIONAL PURPOSES P. Arslanian, P. H. Matin Department of Engineering and Aviation Sciences University of Maryland Eastern Shore Princess Anne, MD-21853, U.S.A.ABSTRACTSenior students in the engineering programs are challenged to thoroughly apply their learnedengineering knowledge and research skills toward design and implementation of a challengingsenior design project. A wind tunnel is often used in mechanical or aerospace engineeringprograms as a laboratory instrument to gather experimental data for investigation of fluid flowbehavior. The authors have involved students to conduct research to implement a comprehensivedesign of a small size wind tunnel for instructional purposes. The objective of this project is toengage the students 1) to design a well-structured wind tunnel model by means of fluidmechanics fundamentals and simulation software, 2) to develop wind tunnel experiments such asflow visualization, lift and drag measurement around different geometries including NACAairfoils. The wind tunnel designed is an open-loop circuit contained of three basic sections: thecontraction nozzle, the working or experiment section, and the diffuser nozzle. Fluid thrust isdelivered by an axial fan attached to the end of the diffuser nozzle. The geometric properties ofthe contraction nozzle and diffuser nozzle are obtained by fluid mechanics theories governing aconstant pressure decrease, or increase respectively. The working section is a duct of constantarea that maintains a uniform fluid velocity. The solid models of the contraction nozzle, workingsection and diffuser nozzle have been built for flow simulation. The performance of the windtunnel designed has been verified through CFD-based simulation. The data collected from thesimulation results indicate that a uniform laminar flow is maintained in the working section asdesired. Different testing models such as sphere and infinite wing have been included in thesimulation to characterize the performance of the wind tunnel during testing. The simulationresults are promising. Extensive engineering knowledge acquired throughout the course ofundergraduate study is applied. Significant experience in the design of wind tunnels has beengained throughout this undergraduate research.
