Abstract
This study conducted experiments to measure pressure drop across a tube bank with tube-to-baffle leakage for various orifice shape factor Z and its effect upon the pressure drop through tube-to-baffle clearance and across the bank is shown. The results show that the former pressure drop for Z=29-55 behaves in a close manner whereas the pressure drop for Z=67 behaves differently from the others, implying laminar flow in the clearance. Meanwhile, it is also shown that the pressure drop across the tube bank is not affected by the Z factor. However, the pressure drop across the tube bank behaves differently when the leakage flows into or out of the tube bank through the clearance. This implies that the leakage has different influence upon the flow field between those two cases.
