Heat Transfer Through Composite Wall By S.k. Appliances

To cater the variegated demands of our precious clients, our organization known as a leading Exporter, Manufacturer, Distributor and Supplier of Heat Transfer Through Composite Wall in Ambala, Haryana, India.
The setup consists of a heater sandwiched between two sets of slabs. Three types of slabs are provided on either sides of heater, which forms a composite structure. A small hand press frame is provided to ensure the perfect contact between the slabs.A variac is provided for varying the input to the heater. Digital Voltmeter and Digital Ammeter display the heat input. Heat produced by heater flows axially on both the sides. Temperature Sensors are embedded at the interfaces of slabs to determine the temperature gradient. The experiment can be conducted at various values of heat input and calculation can be made accordingly.

EXPERIMENTATION:
a cTo determine total thermal resistance and thermal conductivity of composite wall.
a cTo plot temperature gradient along composite wall.
