About Unsteady State Heat Transfer Unit

Unsteady State Heat Transfer Unit

This Unsteady State Heat Transfer Unit has been designed to allow students to run experiments on unsteady state heat transfer. The unit is supplied with a heated water bath and a set of solid shapes with built-in temperature sensor to monitor the temperature at the center of the shape. Monitoring of the temperature at the centre of the shape allows analysis of heat flow using the appropriate transient-temperature/heat flow charts provided.

DESCRIPTION :

Two sets of simple shapes (a solid sphere, a rectangular slab, a long solid cylinder) made of brass and stainless steel are supplied. Each of the shapes has a built-in temperature sensor to measure the temperature at the centre of the shape. Measurements taken on a shape of a particular material can be used to confirm the conductivity of a similar shape of a different material.Transient-temperature/heat flow charts are supplied for each of the shapes.The water bath has a capacity of 30 litres and is heated by a 3.0 kW electric heating element. The temperature of the water bath can be maintained and predetermined by means of a temperature controller before taking any measurements. The large volume of water in the bath ensures that any change in the temperature of the water,as the measurements are taken, is negligible.A circulation pump mounted alongside the water bath circulates water from the bath to the base of a vertical cylindrical duct which is located at the center of the water bath.

SPECIFICATIONS :

A bench top unit designed to allow experiments on unsteady state heat transfer :
a) Bench Made of epoxy coated frame with high quality and sturdy formica laminated back panel.
b) Water Bath: 30 liters insulated stainless steel tank with top plate and mounting for solid shapes. holder Heating is by a 3.0 kW electric heater with high temperature cut-out protection. Water circulation by a circulation pump.
c) Solid Shapes: Two sets of solid shapes made of brass and stainless steel complete with shape holder. Three different shapes i.e. solid sphere, rectangular slab and long solid cylinder. Each solid shape has a built-in temperature sensor at the center.
d) Control Panel: The control panel includes all the necessary electrical wiring, digital indicators and temperature control.

Comprehensive Observation of Unsteady State Heat Transfer

This system empowers users to closely study time-dependent heat transfer processes in a controlled environment. By featuring multiple digital temperature sensors, users can record temperature changes at various points, analyze temperature gradients, and visualize heat flow dynamically. The design also provides straightforward access for data extraction, making it highly effective for lab-based educational activities and research.


Flexible Heating and Cooling Capabilities

Equipped with an immersion heater and internal cooling coil, the unit offers flexible control over thermal cycles from ambient up to 90C. This range allows students and researchers to simulate various real-world scenarios, observe the effects of rapid heating or cooling, and gain a comprehensive understanding of unsteady thermal behavior.


User-Friendly and Safe Operation

Safety is enhanced through features like overheat and low water level protection, as well as a well-insulated construction. The tabletop design ensures ease of installation in any laboratory, while the digital/analog display facilitates immediate temperature readings. Optional data logging allows for advanced analysis, catering to both beginners and experienced users.
