Abstract:

With this project, we would like to design and construct an open wind tunnel having maximum velocity of 15m/s at testing section. Measuring system is also designed and set up so that we can measure aerodynamic forces and moments on testing models, flow velocity and temperature around these models. Various mounting systems are designed to hold testing models according to different testing purposes. This project also includes setting up pressure measurement systems. Pressure at certain point on surface of testing model will be measured by pressure gauge. Then signal from pressure gauge will be transmitted to computer through analogue/digital convert card. A computer program will be written with a module for getting data from pressure gauge and a module for digital signal processing. With this system, we can investigate the pressure distribution over model surface in static and dynamic experiments. Our research group include Prof. Hiromichi Shirato from the Kyoto university, Prof. Hiroshi Kobayashi from the Ritsumeikan university, Dr. Le Thai Hoa from Hanoi Industry University (Vietnam) and 2 doctors from the Ho Chi Minh city University of Technology (Dr. Vu Ngoc Anh & Dr. Tran Tien Anh). The achievement from research project also serve as training and research equipments for our aeronautical students. Each year, our department admits 60 new undergraduate students and 10 students for master program in aeronautical engineering. Among them, 30 undergraduate students are belong to PFIEV (Program de Formation Ingenieur Excellent au Vietname) twining program supported by French government. The complete wind tunnel and measuring system will be used to measure wind loads on scaled models of tall building, tower, long span bridges. Secondly, the dynamic stability of bridges girders will be investigated by using oscillating testing system so that dynamic response of bridges girders will be measured at different wind speeds.
