Dropwise & Filmwise Condensation Apparatus

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.
