"Convection is the mode of energy transfer between a solid surface and the adjacent liquid or gas which is in motion, and it involves the combined effects of conduction and fluid motion. ... In the absence of fluid motion, heat transfer between a solid surface and the adjacent fluid is by pure conduction."
From: Random House Webster's Unabridged Dictionary
con·vec·tion n.
1. Physics. the transfer of heat by the circulation or movement of the heated parts of a liquid or gas.
e·lec·tro·pho·re·sis n.
1. Also called cataphoresis. Physical Chem. the motion of colloidal particles suspended in a fluid medium, due to the influence of an electric field on the medium.
Now, would you be so good as to explain why a definition from a good thermodynamics textbook and a dictionary is not correct. And if you please, also explain what electrophoresis has to do with the definition of convection.

From: Thermodynamics, an Engineering Approach, Yunus A. Cengel and Michael A. Boles, Second Edition, p. 96Wrong. That is not convection.
The requirement of gravity (or acceleration by any means) for convection was studied long ago. A researcher named Lunar demonstrated practical electrophoretic separations about 40 years ago in which he largely negated the adverse effects of convection by having the supporting fluid rotate in a sheet to simulate zero gravity over time. The process was later demonstrated in real microgravity on the shuttle.
