Fluid Mechanics Laboratory

Address:

3rd floor NL-1

Overview:

This lab is run in conjunction with the theory course ME 231 (Fluid Mechanics). It is an introductory course where flow behaviour, fluid forces and analysis tools are introduced. The goals of the experiments include determination of forces generated when fluid flow takes place over a solid object, applications of the control volume approach, demonstration of the momentum and energy equations, viscosity measurement and engineering correlations. Intricate flow phenomena such as separations and transition to turbulence are demonstrated. Experimental setups such as flow through a tube, flow over a flat plate, wind tunnel, smoke tunnel and viscometer are made available to the students. The lab experiments utilize U-tube manometer and digital manometer, a hot-wire anemometer system and data acquisition. The lab runs closely with the lectures in such a way that experiments support the text covered in the class room.

Equipment:

  • Low speed wind tunnel

  • Smoke tunnel

  • Open-channel flow apparatus

  • Jet arrangement

  • Viscometer

  • Reynolds apparatus

  • Digital manometer

  • U-tube manometer

  • Hot-wire anemometer

  • Force transducers

  • Imaging devices

Experiments:

  • Jet impact on flat and curved surfaces

  • Measurement of drag on a circular cylinder in high Reynolds number flow

  • Energy loss measurements in subcritical and supercritical open channel flow

  • Measurement of fluid viscosity

  • Determination of friction factor as a function of Reynolds number in pipe flow

  • Studying laminar-turbulent transition for flow in a tube

  • Boundary layer flow over a flat plate

  • Pressure distribution around a circular cylinder in high Reynolds number flow

The laboratory provides training to undergraduate and graduate students in flow measurements. It boasts of a considerable and diverse collection of imaging equipment, many of them developed within the laboratory itself. The areas of research include flow imaging, control, jets and wakes, micro-scale transport, and interfacial fluid dynamics. It has good computational facilities as well. A large number of Master’s and doctoral students have graduated over the years and flourish professionally around the world. The faculty has collaborated with organizations such as DRDL Hyderabad, SSPL, New Delhi, BARC Mumbai, RRCAT Indore, IGCAR Kalpakkam within the country. International partners include ETH Zurich, Kyoto University, Japan, and University of Minnesota, USA. Recently, the faculty has started collaborative projects with the private industry in solar energy, biomedical equipment, and diamond characterization.
