Fluid Dynamics Laboratory
- The Fluid Dynamics Laboratory consists of flow measurement devices, head loss measurement in pipe flow, impact of water jet on vanes, flow visualization apparatus, hydraulic pumps and turbines. The students will experimentally demonstrate the knowledge gained from fluid mechanics. The students are encouraged to operate the experimental test rig to know the operational procedures and to familiarize the working principle with performance calculations

Research Facilities in The Laboratory
DESCRIPTION: CAVITATION TEST RIG
EQUIPMENT SPECIFICATIONS:
- Motor Rating: 2.2 kW, 1 Phase
- Motor Rated Speed: 2700 RPM
- Motor efficiency: 0.85
- Pipe Diameter: 25 mm
- Throat Diameter: 6 mm
- Collecting Tank Area: 0.5 m x 0.3 m x 0.4 m
- Reservoir Tank size: 1.2 m x 0.6 m x 0.3 m
BENEFITS OF THE RESEARCH EQUIPMENT:
- Using this test rig, cavitating flow can be observed for inception (less bubble) to developed cavitation (more bubble) stage. The control range of the test rig is sufficient to obtain an intensive and broad cavitating cloud at nozzle throat. Using the measuring system of the test rig, essential data like fluid flow rate, upstream and downstream pressure of the cavitation chamber can be obtained.
DESCRIPTION: Free and forced vortex flow visualization test rig
EQUIPMENT SPECIFICATIONS:
- Drum Diameter: 0.3 m (2 Nos)
- Motor Rating: 180 W, 1 Phase
- Motor Rated Speed: 2700 rpm
- Pump capacity: 2000-3000 LPH @ head 3-24 m
- Reservoir Tank size: 0.3 m x 0.2 m x 0.2 m
BENEFITS OF THE RESEARCH EQUIPMENT:
- This equipment enables students to produce both free and forced vortices and show vortex water surface profile. When the vessel rotates, water passes through the perforations and spirals slowly inwards to a small hole in the center of the base of the vessel. The surface falls rapidly towards the center and produces an air core. Students measure the surface profile using the traverse probe.
DESCRIPTION: REYNOLD’S APPARATUS
EQUIPMENT SPECIFICATIONS:
- Pipe Diameter: 32 mm
- Motor Rating: 0.37 kW (1)
- Pump capacity: 1.35 lit/sec @ head 12 m
- Collecting Tank Area: 0.3 m x 0.3 m
- Reservoir Tank size: 2 m x 0.3 m x 0.3 m
- The kinematic viscosity of water: 1.01 x 10-6 m2/s
BENEFITS OF THE RESEARCH EQUIPMENT:
- The goals of the present experiment are to visualize dye mixing for flow in a tube under laminar and turbulent conditions and carefully estimate the critical Reynolds number below which flow is laminar and above which it is turbulent.
