An experimental investigation of outflow of liquids from single-outlet vessels (1995)
Journal Article
Schmidt, O., & Kubie, J. (1995). An experimental investigation of outflow of liquids from single-outlet vessels. International Journal of Multiphase Flow, 21(6), 1163-1168. https://doi.org/10.1016/0301-9322%2895%2900051-x

This paper considers the outflow of a liquid from a single outlet vessel, i.e. a vessel in which the outflowing liquid is displaced by another fluid which enters the vessel through the same opening. The simplest possible arrangement is investigated:... Read More about An experimental investigation of outflow of liquids from single-outlet vessels.

Effect of Vortices on Liquid Outflow from Vessels (1995)
Journal Article
Harvey, R., & Kubie, J. (1995). Effect of Vortices on Liquid Outflow from Vessels. Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 209(5), 363-370. https://doi.org/10.1243/pime_proc_1995_209_164_0

This paper considers the effect of vortices on liquid outflow from open vessels. One of the simplest possible arrangements is investigated: an axisymmetric vertical cylindrical vessel with an outlet in its base. A simple spiral vortex is either intro...

Influence of containing walls on the distribution of voidage in packed beds of uniform spheres (1988)
Journal Article
Kubie, J. (1988). Influence of containing walls on the distribution of voidage in packed beds of uniform spheres. Chemical Engineering Science, 43(6), 1403-1405. https://doi.org/10.1016/0009-2509%2888%2985113-3

The distribution of voidage in the wall regions of randomly packed beds of uniform spheres is investigated. A general equation relating the local voidage to the distribution of the spheres is derived and is combined with some simple observations abou...

Steady-state conduction in stagnant beds of solid particles (1987)
Journal Article
Kubie, J. (1987). Steady-state conduction in stagnant beds of solid particles. International Journal of Heat and Mass Transfer, 30(5), 937-947. https://doi.org/10.1016/0017-9310%2887%2990012-3

A model is developed for predicting the influence of the containing walls on heat transfer processes in stagnant beds of solid particles. The model describes the effect of the walls on the mean voidage of the bed and on the mean effective thermal con... Read More about Steady-state conduction in stagnant beds of solid particles.

Heat transfer between gas fluidized beds and immersed surfaces (1985)
Journal Article
Kubie, J. (1985). Heat transfer between gas fluidized beds and immersed surfaces. International Journal of Heat and Mass Transfer, 28(7), 1345-1353. https://doi.org/10.1016/0017-9310%2885%2990165-6

Various models of heat transfer between the emulsion phase of a gas fluidized bed and immersed surfaces are discussed. It is shown that certain features of these models, such as the contact resistance or a gas film between the surface and the solid p...

Axisymmetric outflow from large vessels (1984)
Journal Article
Kubie, J. (1984). Axisymmetric outflow from large vessels. Proceedings of the Institution of Mechanical Engineers. Part A, Power and process engineering, 198(5), 113-119. https://doi.org/10.1243/pime_proc_1984_198_016_02

A model of axisymmetric liquid outflow from large vessels is developed and is used to explain aspects of flow for self-venting and choked outlets. It is shown that for flows with self-venting outlets the model relates the liquid level to the flow. It... Read More about Axisymmetric outflow from large vessels.

Performance and design of plug‐type check valves (1982)
Journal Article
Kubie, J. (1982). Performance and design of plug‐type check valves. Proceedings / Institution of Mechanical Engineers, 196(1982), 47-56. https://doi.org/10.1243/pime_proc_1982_196_006_02

Plug check valves are frequently used in high pressure systems where parallel pump operations are envisaged, in order to prevent flow recirculation through the out-of-service pump. Serious operational problems are sometimes encountered with these val... Read More about Performance and design of plug‐type check valves.
