Heat Transfer Coefficient in Downward Flow Vertical Liquid Film Type Evaporator

Visual Observation of Flow Regime Transition in Downward Vertical Gas-Liquid Flow Using Simple Mixer

Different flow patterns of downward gas-liquid two-phaseflow using simple mixer are studied in an experimental manner. An experimental setup is designed and fabricated to allow the visual observation of downward two-phase flow patterns and their transitions. The flow patterns are recorded by a 1200 frames per second high speed video camera. The quality of downward two-phase flow patterns photos...

Mechanistic Modeling of the Liquid Film Shape and Heat Transfer Coefficient in Annular-Regime Microchannel Flow Boiling

Heat Transfer, Mass Transfer and Scaling Characteristics in a Long Tube, Climbing Film, Pilot Plant Evaporator

ing characteristics could be investigated. Finally the pilot plant A single tube plant Kestner evaporator'was set up at was run under 1st effect conditions in order that a comparison Illovo to investigate heat transfer characteristics when could be made with industrial 1st effect evaporators (both simulating different evaporator Tests carried out have Roberts and Kestner). This particular trial...
