Settling velocity of droplets in turbulent flows (1980)
Journal Article
Kubie, J. (1980). Settling velocity of droplets in turbulent flows. Chemical Engineering Science, 35(8), 1787-1794. https://doi.org/10.1016/0009-2509%2880%2985016-0

Two parameters of particle or droplet dynamics which are of importance in describing their behaviour in turbulent pipe flows are their settling velocity and eddy diffusivity. It is usually assumed that the settling velocity in turbulent flow is equal... Read More about Settling velocity of droplets in turbulent flows.

Two-phase steam-water flow through Y-junctions (1979)
Journal Article
Kubie, J., & Oates, H. (1979). Two-phase steam-water flow through Y-junctions. International Journal of Heat and Fluid Flow, 1(4), 161-167. https://doi.org/10.1016/0142-727x%2879%2990004-3

An investigation has been made of steam-water flow in a vertical coplanar Y-junctions which are used, for example, in the condensate carrying pipework downstream of direct contact heat exchangers. The steam-water flow is stratified in the sloping lim... Read More about Two-phase steam-water flow through Y-junctions.

The presence of slug flow in horizontal two-phase flow (1979)
Journal Article
Kubie, J. (1979). The presence of slug flow in horizontal two-phase flow. International Journal of Multiphase Flow, 5(5), 327-339. https://doi.org/10.1016/0301-9322%2879%2990011-9

One of the flow regimes occurring in horizontal two-phase flows is characterized by periodic large waves “surging” along the tube. This flow, called “slug” flow, has been frequently observed in low and high pressure gas liquid systems, but it has bee... Read More about The presence of slug flow in horizontal two-phase flow.

Two-phase gas-liquid flow through Y-junctions (1978)
Journal Article
Kubie, J., & Gardner, G. (1978). Two-phase gas-liquid flow through Y-junctions. Chemical Engineering Science, 33(3), 319-329. https://doi.org/10.1016/0009-2509%2878%2980089-x

An investigation has been made of air-water flow in Y-junctions, which are frequently used in industrial applications. The air-water flow is stratified in the sloping limbs approaching the junction and this paper examines the phenomena occurring at t... Read More about Two-phase gas-liquid flow through Y-junctions.

Drop sizes and drop dispersion in straight horizontal tubes and in helical coils (1977)
Journal Article
Kubie, J., & Gardner, G. (1977). Drop sizes and drop dispersion in straight horizontal tubes and in helical coils. Chemical Engineering Science, 32(2), 195-202. https://doi.org/10.1016/0009-2509%2877%2980105-x

Measurements were made of the size distribution and maximum size of drops in liquid-liquid systems. The data on the maximum drop size, together with other data available in the literature, are assessed in the light of Hinze's [1] theory. It is shown...

Flow of two liquids in a helix: an analogue of high pressure helical boilers (1977)
Journal Article
Kubie, J., & Gardner, G. (1977). Flow of two liquids in a helix: an analogue of high pressure helical boilers. International Journal of Multiphase Flow, 3(4), 353-366. https://doi.org/10.1016/0301-9322%2877%2990015-5

It has been shown previously (Gardner & Kubie 1976) that a two-liquid system provides a better analogue for investigating certain aspects of high pressure boiler tube hydrodynamics than air and water at atmospheric pressure. A study is presented here... Read More about Flow of two liquids in a helix: an analogue of high pressure helical boilers.

Bubble induced heat transfer in gas fluidized beds. (1976)
Journal Article
Kubie, J. (1976). Bubble induced heat transfer in gas fluidized beds. International Journal of Heat and Mass Transfer, 19(12), 1441-1453. https://doi.org/10.1016/0017-9310%2876%2990074-0

The influence of gas bubbles on heat transfer in gas fluidized beds has been investigated. A platinum wire has been used as a heat-transfer probe and the aggregative gas fluidized bed has been simplified by generating a single continuous stream of ga...

Flow of two liquids in sloping tubes: An analogue of high pressure steam and water (1976)
Journal Article
Gardner, G., & Kubie, J. (1976). Flow of two liquids in sloping tubes: An analogue of high pressure steam and water. International Journal of Multiphase Flow, 2(4), 435-451. https://doi.org/10.1016/0301-9322%2876%2990024-0

A two-liquid system provides a better analogue for visualization purposes of high pressure boiler systems, where the density ratio is typically 4:1, than air and water at atmospheric pressure. A study is presented of the flow of isoamyl alcohol and w... Read More about Flow of two liquids in sloping tubes: An analogue of high pressure steam and water.
