DROPWISE CONDENSATION OF STEAM ON A SMALL TUBE BUNDLE AT TURBINE CONDENSER CONDITIONS

摘要

Application of dropwise condensation to utility turbine condensers is investigated by comparing the thermal performance of dropwise and filmwise bundles at industrially relevant conditions. Steam and steam-air mixtures were condensed on bundles of in-line, titanium tubes. The row-by-row heat transfer coefficients are presented against bundle position.
