Drop Wise and Film Wise Condensation Apparatus
Description of Drop Wise and Film Wise Condensation Apparatus :
- Condensation is a phase change heat transfer process occurring in many industrial applications, such as in steam power plants, refrigeration plants etc.
- Thus this is one of the important heat transfer process as present in mechanical and chemical engineering applications.
- The condensation of vapour on a surface is of two types: 1. Drop wise Condensation, 2. Film wise Condensation.
- This setup is designed for determining heat transfer co-efficient of two types of condensation and for visualization of these processes.
- It consists of a vertical frame. Condensation tubes are fitted inside compact glass cylinder.
- Steam generator is fitted at the backside of the cylinder. Steam comes directly from generator to the cylinder.
- Two valves are fitted to control flow rate of water in individual tubes
- Digital Temperature Indicator monitors the temperatures.
- Pressure gauge and Rotameter can observe steam pressure and cold water flow rates respectively
- A Digital temperature Controller is provided for controlling the temperature of Steam
- Water level indicator is provided in steam generator
- Condensate is measured by a measuring cylinder
Experimentation:
- To study the Film wise & Drop wise condensation of steam on a vertical surface.
- Visualization of condensation process in drop wise as well as film wise condition.
