DROPWISE / FILMWISE CONDENSATION APPARATUS
Model No: HT-012
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.
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 Rota meter 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.
