Flow Visualization Wind Tunnel
The apparatus is intended for visualization of stream lines flow around models.
The apparatus consists of a stilling entrance, a contraction section with air flow straighteners, a streamlines distributor, a viewing window, and a smoke generator.
Air flow is generated by a fan. The window has a black back ground and side lights are provided for better visualization of the streamlines. The stream lines are in a vertical pattern. Models are provided.
Instruction manual is also included.
TYPICAL EXPERIMENTS
- Laminar and turbulence flow observation.
- Flow patterns around bodies.
- Boundary separation on bodies.
- Effects of angle of attack.

Air Flow and ThermodynamicsShell and Tube Heat Exchanger
The apparatus is used for studying heat transfer through a shell and tube heat exchanger under parallel or counter flow conditions.
The unit consists of a shell and tube heat exchanger and a service module. The module comprises a hot water tank with a transfer pump and instruments for monitoring and control. Parallel and counter flow is by switching cold water hoses with quick coupling. The unit requires outside water supply.
Instruction manual is also included.
TYPICAL EXPERIMENTS- Demonstration of heat transfer under parallel and counter flow.
- Determination of heat transfer coefficient.
- Effects of flow rate and temperature difference.
TECHNICAL DATAConstruction arrangement Insulated stainless steel shell with 7 stainless steel inner tubes Service module consisting of: – Hot water pump. – Heater 3000 W. – Flow meters - Hot water
- Cold water
– Temperature control un . it to limit temperature of hot water to not more than 80°C Software for data display and analysis by computer (separately supplied). Power supply 220 V, 1 Ph, 50 Hz. Other power supply is available on request. (0 reviews) -
