Abstract: It was an honor to receive the Max Jakob Memorial Award for 2018. This invited paper is based on the award lecture and is written in an informal style expanding on the lecture and focusing on work in which I have been ...

Abstract: A theoretically based, approximate solution for condensation on horizontal, microfinned tubes has been used as a basis to obtain a relation between heat flux and vapor-surface temperature difference for condensation on a ...

Abstract: A relatively simple theory of annular laminar film condensation in microchannels, based on the Nusselt approximations for the condensate film and a theoretically based approximation for the vapor shear stress, has no ...

Abstract: Careful heattransfer measurements have been conducted for condensation of steamethanol mixtures flowing vertically downward over a horizontal, watercooled tube at pressures ranging from around atmospheric down to 14 kPa. ...

Abstract: The paper reports calculations of friction pressure gradient for the special case of laminar annular flow condensation in microchannels. This is the only flow regime permitting theoretical solution without having recourse ...
