An experimental study of friction factors and mixed convection in the thermal entrance region of vertically narrow, horizontal rectangular channels for different heating conditions and aspect ratios

Creator:: Hong, Seung-Ho
Abstract:: Heat transfer and fluid mechanical behavior of water flowing horizontally in vertically-narrow rectangular channels was studied in this work. Friction factor and Nusselt number variations were determined experimentally for four different wall heating conditions, and for aspect ratios(height to width) of 5, 4, 3, 2, and 1. Wall heating conditions...

Dislodgement and deformation of microbubbles in laminar channel flow

Creator:: Tence, David A.
Abstract:: In this thesis the critical parameters involved in the dislodgement and deformation of microbubbles in laminar channel flow, are determined and evaluated. Experimentally the effects of surface tension, viscosity, fluid flow rate, density, and bubble diameter on bubble dislodgement were evaluated. A theoretical scale analysis was performed which provided a...

A numerical model for predicting energy dispersion in thermal plumes issuing from large, vertical outfalls in shallow coastal water

Creator:: Trent, Donald S.
Abstract:: A theoretical study of the heat and momentum transfer resulting from a flow of power plant condenser effluent discharged vertically to shallow, quiescent coastal receiving water is presented. The complete partial differential equations governing steady, incompressible, turbulent flow driven by both initial momentum and buoyancy are solved using finite-difference techniques...

The effect of entrance configuration on local heat transfer coefficients in subsonic diffusers

Creator:: Stoffel, Edward Oswald
Abstract:: The effects of round, square, and reentrant entrances on flow regimes and local heat transfer coefficients were determined using a symmetrical, plane-wall two-dimensional, subsonic air diffuser with one of the diverging walls heated and maintained isothermal. Flow and heat transfer studies were made at total divergence angles ranging from 0...

Cold trap performance : a general analysis

Creator:: Rothwell, Micheal Olin
Abstract:: A cold trap is a device used to remove certain impurities from a liquid metal by controlled precipitation of such impurities. An investigation of the thermal characteristics of laminar flow in two air-cooled cold traps was made. This investigation showed that the sodium heat transfer rate is a function of...
