The Forced Convection Apparatus is designed to study convective heat transfer from a heated surface to a fluid under forced flow conditions. It allows students to understand the heat transfer process, verify theoretical correlations, and determine heat transfer coefficients under different airflow rates.

Educational Objectives

• Understand principles of forced convection heat transfer.

• Study the effect of air velocity and surface temperature on heat transfer.

• Determine heat transfer coefficients under laminar and turbulent flow.

• Verify theoretical correlations of Nusselt, Reynolds, and Prandtl numbers.

Performance Measurement

• Surface and fluid temperature measurement at various points.

• Air velocity control and measurement.

• Calculation of heat transfer coefficients.

• Comparison of experimental and theoretical results.

Panel and Instruments

• Horizontal duct with electric heater and test section.

• Blower unit with variable speed control.

• Thermocouples at inlet, outlet, and along the test surface.

• Digital temperature indicator.

• Voltmeter and ammeter for electrical measurements.

• Airflow measurement device (orifice meter / anemometer).

• Safety features with overload protection.
