Creator:: Yarger, David J.
Abstract:: Driven by the need for high energy-density power sources, demand has stimulated the development of small-scale engines. A small-scale engine with a fuel supply could replace batteries and utilize higher energy-density liquid hydrocarbon fuels; such an advance could deliver a new age of portable devices. Currently, operable small-scale engines exist;...
Resource Type:: Masters Thesis
Full Text:: feature of the invention was to economize the thermodynamic cycle by using an internal heat exchanger

Creator:: Bae, Young Lib
Abstract:: This thesis examines the transient and steady-state temperature performance of a rotary regenerative heat exchanger. In contrast to previous studies on this problem, fluid flow in the circumferential direction was considered. Appropriate modeling was included to measure the effect of carry-over on the differential equations describing mass and energy conservation....

Creator:: Aceves, Salvador M.
Abstract:: The problems of freezing and melting present special mathematical complexity and, except for the most elementary one-dimensional cases, require a numerical solution. However, these problems have a growing importance in engineering problems because of their application to metallurgical operations, food preservation, heating and air conditioning, etc. In the present work,...

Full Text:: Mathematical Description of the Model The equations governing the flow and heat transfer in the evaporator

Creator:: Young, Eric P.
Abstract:: Two-phase flow in helical conduits is important in many industries where reaction between components, heat transfer, and mass transport are utilized as processes. The helical design is chosen for the effects of secondary flow patterns that reduce axial dispersion, increased heat transfer, and also their compact design. The first is...
Resource Type:: Dissertation
Full Text:: exchanger design it increases laminar heat transfer while extending the Reynolds number range of laminar

Creator:: Jenks, Jeromy W.
Abstract:: An experimental study of absorption of ammonia into a constrained thin film of ammonia-water solution is presented. A large aspect ratio microchannel with one of its walls formed by a porous material is used to constrain the thickness of the liquid film. Experiments were performed at a pressure of 1,...
