Continuous Reactor an overview ScienceDirect Topics

Fluid flow in a continuous reactor is a very complex physical phenomenon that has direct impact on chemical reactions taking place inside the reactor including both reaction rate and the extent of the reactions Such an impact can be understood by examining the velocity distribution inside the reactor It is well known that for fluid flow inside a tube the radial distribution of velocity is
