How to interpret the mass transfer from gas to solid particles in the fluidized bed? Does it mean some gas molecules enter the surface of the particles, say catalyst particles? -----Tim Lee

Hm. In astronomy, "mass transfer" usually refers to situations where plasma from one source, e.g. a star, is gravitationally attracted to, and eventually accreted onto, another source. It's a situation that commonly happens in binary star systems. However, I tried to phrase this as a formal explanation and wasn't satisfied with any of my own attempts. Could the astronomy-knowledgeable lend a hand? -- April

How about

In astronomy, mass transfer is the process by which matter gravitationally bound to a body, usually a star, fills its Roche lobe and becomes gravitationally bound to a second body, usually a compact object (white dwarf, neutron star or black hole), and is eventually accreted into it. It is a common phenomenom in binary systems, and may play an important role in some types of supernovae, and pulsars.--AstroNomer

  • Much better than any of my drafts! :) I went ahead and included it, linking "Roche lobe" to "Roche limit". I figure that folks will continue to edit it in the Wiki way. :) -- April

Problems with the engineering[edit]

Mass transfer occurs due to differences in chemical potential, not concentration. (Otherwise how would the stars in the astrophysics section form?) I'm not sure what's going on with this page. Is the "Common Types of Mass Transfer" section incomplete? ChE Fundamentalist (talk) 19:48, 31 July 2011 (UTC)[reply]

Article Selection[edit]

The Chemical Engineering section is very ambiguous in terms of what its been talking about. I would recommend to add how heat transfer relates to mass transfer. How the gradients of concentration can relate to the gradient of temperature in a control volume. Perhaps giving an example of a common chemical engineer control volume such as a CSTR, where you define the mass balances,mole balances and the temperature balance showing how they relate to each other. To add more mathematics behind the concept , you could also solve the system of equations by using Laplace transformers ( this could make the subject a little bit more mathematically complex) but your readers with a chemical engineer background can appreciate it.

Transfer through solids[edit]

Can we add a section on mass transfer through solids and the factors affecting their rates. I came across mass transfers in a page on super critical fluids and I was hoping it was elaborated here. Clepenji1150 (talk) 12:17, 30 June 2023 (UTC)[reply]
