求助看这是什么意思? 参考下面: remove tubes to create bypass lanes for a heat exchanger with a tube vibration problem caused by fluidelastic instability, creating artificial bypass lanes in the window area is an effective temporary remedy. first, remove tubes in the window areas to create a lane from the baffle tip to the shell parallel to the direction of flow. then plug the tube sheet where tubes were removed. allow additional bypassing; do not seal the holes in the baffles. this temporary solution, which lowers shellside pressure drop and reduces shellside thermal performance, is particularly attractive when the heat exchanger is tubeside heat transfer limited.查看更多
