DESCRIPTION:

“WIND TUNNEL” has been developed to perform various experiments of aerodynamics and fluid flow. This is a open circuit Wind Tunnel provides a region of controlled air flow into which models can be fitted at downstream of working section. The Tunnel consists of bell mouth shaped entry to guide the air smoothly into settling chamber and stabilizes the air flow this follows working section for test section where various models can be tested. Test section with acrylic sheet, will be provided for visual observation. Working section is followed by diffuser section which reduces the dynamic pressure at the exit. A fan coupled with motor is used to produce desired wind velocity.

The present set-up has a facility to interface the system with computer which enables to log the experimental data using computer. The educational software and data-logging package has been developed for unit. The software environment base is of Lab view of NATIONAL INSTRUMENTS, USA. This software is compatible to interfacing unit designed by “Lab Smith”. This software package provides a comprehensive educational software environment within which the investigations can be performed. This software is capable to tabulate the sample readings according to the requirement of experiment under study and results obtained can be compared. The real time data acquisition can be done by interfacing the set-up with computer using software. Software allows the user to have control on data logging, printing the stored data, preparing spread sheets in Excel etc.
