Dropwise & Filmwise Condensation Apparatus

About Dropwise & Filmwise Condensation Apparatus

Dropwise & Filmwise Condensation Apparatus:-

Description:

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.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.

Technical Specifications:

Steam Generator:

• 8 Ltrs. (Approx.) made of Stainless steel with 1.5 kW heater.
• Insulated with ceramic wool and cladded by aluminum foil.

Pressure Gauge:

• Bourdon type Copper tubes (2 Nos.).
• One with natural finish and other nickel polished Diameter.
• 19 mm (Approx.)Length: 170 mm (Approx.)Water Flow measurement.
• Rota meter Condensate Measurement: Measuring Cylinder & Stopwatch Control valves.
• one each for Steam, Cooling water & Drain Digital Temp. Controller.
• 0-199.90C (For Steam Generator)Digital Temp. Indicator: 0-199.90C, with multi-channel.

Direct Observation of Condensation

Thanks to tempered glass windows, users can directly monitor both dropwise and filmwise condensation phenomena in real time. This transparency allows for a clear comparison between the two types and fosters deeper understanding during practical exercises or classroom demonstrations.


Robust Safety and Precision Features

The apparatus is equipped with over-temperature protection and insulated electrical components to prioritize operator safety. High-quality copper cylinders, stainless steel heat exchangers, and a sturdy mild steel frame ensure both accuracy and reliability across a range of experiments.


Comprehensive Learning Resource

A detailed experimental manual accompanies the equipment, supplying theoretical background, step-by-step procedures, and calculation examples. This resource transforms the apparatus into a versatile teaching tool for thermodynamics and heat transfer courses.
