Fluerics 36:Large-Scale Modeling of Laminar Flueric Devices.

摘要

The purpose of this report is to investigate large-scale modeling of laminar flueric flow phenomena. A test facility using silicone oil as the working fluid and Reynolds number as the modeling parameter was designed,constructed,and instrumented. The test facility described is inexpensive and easy to operate. Models can be readily inserted,tested,and modified for retesting. In order to test the validity of modeling,performance characteristics of a large-scale model and an existing laminar-air proportional amplifier were compared. Agreement between similar performance characteristics was very good,with differences accounted for by experimental error and the existence of small variation in geometric similarity between the model and air device. Results obtained thus verify that the laws of similitude are valid for the conditions specified,and can be readily used. (Author)
