Plenum chamber flow losses in forced draught air-cooled heat exchangers

摘要: The primary objective of this experimental investigation is to determine the influence that different fan and heat exchanger characteristics as well plenum chamber geometry have on flow losses in a forced draught air-cooled (ACHE). effect air maldistribution thermal performance also investigated. A series model tests are conducted employing fans exchangers. It found there critical minimum distance between outlet exchanger. loss coefficient its inlet relatively strong velocity distribution at Other variables, including position casing, fan-to-heat area ratio characteristics, lesser performance. recovery defined expressed terms measured parameters. This can be employed design practical ACHEs. further only has small
