  1. National Wind Tunnel Facility, IITK Journey so far & Its Mission Past, Present, and Future Dr. K. Poddar

  2. Presentation Overview • Introduction • Report on NWTF activities (2006 – 2008) • Projected Activities for next 3 years (2009 – 2011) • Strengthening NWTF team • Proposed HRD Plan • Proposed Academic Programs • Proposed Expansion Programs • Experimental Facilities • Computational Facilities • Design & Inspection Facilities NWTF (IITK)

  3. Background • National studies coordinated under the auspices of AR&DB in the late eighties identified a strong need for a low speed wind tunnel in India to provide Indian Industry with adequate support in experimental aerodynamics for effective development work. Thus, a National Wind Tunnel Facility Project (NWTF-P) was initiated. • NWTF was conceived as an autonomous activity at IIT Kanpur in the academic environment, with the objective to construct, operate, maintain and further develop the wind tunnel facility as a Users’ Facility. • Further, due to funding constraints it was decided to implement the project in two phases as follows: Phase I • Tunnel circuit, fan, motor, and drive system • Model support mechanism, turntables, and instrumentation Phase II • Test section parking hall and tunnel control room • Instrumentation and calibration rooms • Model design, inspection, integration rooms and model shop • Wind tunnel offices, conference room, model display room NWTF (IITK)

  4. National Wind Tunnel Facility Established in 1999 with the financial support from AR&DB, DST, and IIT Kanpur, the National Wind Tunnel Facility (NWTF) has unique and nationally recognized capabilities to evaluate aerodynamic performance of flight and road vehicles as well as wind effects on civil engineering structures. • Special Capabilities • Full-model testing with sting support system • 2-D model testing using turntables • Open jet testing • Flow diagnostic using PIV & visualization • Ground effect simulation with moving belt • Gust and cross-wind simulation • ABL simulation for civil applications • Important features • High Reynolds Number simulation • Very low turbulence • Interchangeable mobile test sections • Automated measurement & control systems NWTF (IITK)

  5. National Wind Tunnel Facility NWTF is committed to take up sponsored and consultancy projects of national importance as well as supporting academic research at IIT Kanpur. • Major contributions • In house R&D activities through sponsored and consultancy projects • Interdisciplinary and Inter-departmental interaction through support for PG Students’ Thesis and faculty R&D projects • R&D support for National Aerospace Programs of ADA, ADE, ADRDE, ARDE, DRDL, NAL, VSSC • R&D support to Civil Engineering industry • HRD through short courses and symposiums Space Capsule Recovery Experiments • Active Research Areas • Decelerator aerodynamics, unsteady and high angle • of attack aerodynamics, Low Re aerodynamics, flow • controls, ground effect on flight and road vehicles, • Automobile aerodynamics wind effect on structures, • virtual instrumentation LTA on Sting Support System NWTF (IITK)
