Cross Flow Water to Air Heat Exchanger Setup
Automotive radiators, air conditioning condensers, and industrial air heaters all rely on the efficiency of cross-flow heat exchange. Our Cross-Flow Heat Exchanger Apparatus is designed to replicate these real-world systems in a laboratory setting. Unlike shell-and-tube exchangers where fluids flow parallel, this setup demonstrates the complex thermodynamics where the cooling air flows perpendicular to the hot liquid tubes. Theoretically, the apparatus allows students to investigate the unique challenges of Cross-Flow configurations (both mixed and unmixed fluids). The Theory: Students apply the Log Mean Temperature Difference (LMTD) method with a Correction Factor (F) to calculate heat transfer: The Experiment: By varying the air velocity and water flow rate, students analyze how the Overall Heat Transfer Coefficient (U) changes and study the trade-off between heat transfer efficiency and pressure drop (pumping power) across the tube bank
