ABSTRACT	ESDU 92035 provides details of a Fortran program provided on disc in the software volume (ESDUpac A9235) both uncompiled and compiled within ESDUview, a user-friendly interface that prompts for input data on-screen and runs under MS DOS. It implements the calculation procedure of ESDU 83004. It allows performance analysis of an existing design, or the design of a bearing to meet selected performance requirements in which case suitable bearing dimensions, subject to any space constraint, are recommended. The predicted performance includes the lubricant film thickness under load, its temperature and flow rate, the power loss, and the bearing temperature. Recommendations are also made on surface finish. Warning messages are output in the following cases, for each of which possible remedial actions are suggested: drain or pad temperature too high, churning losses too great, film thickness too small, pad number too high, ratio of inner to outer pad radius too large, flow rate too great, lubricant or pad temperature outside usable range. A lubricant database is provided that may be extended or edited. The program applies to Newtonian lubricants in laminar flow. Worked examples illustrate the use of the program.
