Experimental data are reported for boiling water and a glycerol-water mixture at a free surface pressure of 50 mbar absolute on the shell-side of a thin slice model of an industrial boiler. The boiler test section was 1 m high, 0.75 m wide, 98 mm lon

Experimental data are reported for water boiling at pressures of 850 and 50 mbar absolute on the shell-side of a model industrial boiler slice. The boiler test section was 1 m high, 0.75 m wide and contained 36 electrically heated tubes. The tubes we

The two-fluid model is applied to a thin sliced kettle reboiler. The tube bundle is treated as a porous medium in which the drag coefficient and tube-wall force are deduced from the empirically-based, one-dimensional model. Methods available in the o

The paper presents the results of numerical calculations for filmwise condensation of downward flowing pure saturated steam on a horizontal tube. A tube of 19.05 mm diameter was used. Steam approach conditions used were 5000 N/m 2 (T sat = 32.9 o C)

In condensation over horizontal tubes where the wall temperature is not measured directly, the Wilson plot is used to determine the cooling side heat transfer coefficient. Conventionally, the variation in Nusselt number, Nu, with condensate side temp

A one-fluid, or algebraic slip, model has been developed to simulate two-dimensional, two-phase flow in a kettle reboiler. The model uses boundary conditions that allow for a change in flow pattern from bubbly to intermittent flow at a critical super

The paper describes tests boiling R 113 at atmospheric pressure in upward flow over a 17 row column of square pitched electrically heated tubes. Uniform heat fluxes of 10–65 kW m–2 and maximum Reynolds numbers, Remax, between 7800 and 27 000 were

A particle image velocimetry (PIV) autocorrelation technique was applied to produce whole field vector maps of flow beneath and to the side of a 17 row × l7 column kettle reboiler thin slice rig, boiling pentane at atmospheric pressure. The flow pro

Pressure drop measurements were carried out in a test condenser of staggered configuration with p/D = 1.33. The test conditions were: steam inlet pressure, 50 mbar, inlet velocity 10-30 m s -1 and steam-to-cooling water temperature difference 5-15 K.

An experimental study has been undertaken into the enhancement obtained in the heat-transfer coefficients when HIGHFLUX tubes are used in preference to plain tubes while boiling pentane. The study involved two experimental facilities, a single-tube p
