Electrostatic Heat Transfer Enhancement in a Tube Bundle Gas-to-Gas Heat Exchanger
摘要
Enhancement of heat transfer rates on the tube and shell sides of a bank of seven tubes in a gas-to-gas heat exchanger was investigated experimentally using the electrostatic (also referred to as the electrohydrodynamic or the EHD) technique. Using a novel method, it is demonstrated that the current in each tube, and therefore the corresponding heat transfer enhancement rates, can be controlled independently. Heat transfer enhancement rates were studied as a function of the Reynolds number (ranging from Re = 1000 to Re = 6,000) and the applied electric field current (ranging from threshold value to the near spark-over limit) in the tube and shell sides. It was found that enhancements were highest at the lowest Reynolds number and under highest applied electric field intensity. The simultaneous excitation of the tube and shell sides led to maximum enhancement in the overall heat transfer coefficient.
