Energy Equations

A steady-state model of a conventional floating ring bearing is presented, specifically, to assess the feasibility of its use in the power generating industry. It necessitates the numerical solution of the Reynolds and energy equations for both inner and outer lubricant films. Oil recirculation and heat and mass transfer between the films are included. For the application considered, the oil temperatures and eccentricity ratios encountered are not excessive.

Difference Solution

A heuristic “pseudo-steady-state” model of the heat and mass transfer occurring in desiccant dehumidifiers, embodied in the program DESSIM, has been proposed as a conceptually and numerically simple analysis tool (Barlow, 1982). A comparison is made with a finite difference solution to determine the accuracy and limitations of the pseudo-steady-state model. The comparison indicates that the pseudo-steady-state model can produce accurate results of dehumidifier performance relative to the finite difference solution when used carefully, although at greater computational expense. Substitution of the finite difference solution into the overall DESSIM program results in a potentially accurate and useful analysis tool.

Volume Response

A steady-state model coupling mass transfer across cell and fiber membranes is theoretically developed to investigate the removal process of cryoprotective agents (CPAs) from cryopreserved blood with hollow fiber modules, and then CPA concentration variation and cell volume response are studied.
