Viscosity Measurement in Thin Lubricant Films Using Shear Ultrasonic Reflection
When a shear ultrasonic wave is incident on a solid and liquid boundary, the proportion that is reflected depends on the liquid viscosity. This is the basis for some instruments for on-line measurement of bulk liquid viscosity. In machine elements, the lubricant is usually present in a thin layer between two rubbing solid surfaces. The thin film has a different response to an ultrasonic shear w...
متن کاملIn situ Simultaneous Measurement of Temperature and Thin Film Thickness with Ultrasonic Techniques
A novel technique to measure in situ, simultaneously, temperature and thin film thickness during semiconductor processing is described in this paper. The measurement technique is based on the principle propagating in a silicon wafer is a function of both the that the velocity of an ultrasonic Lamb wave wafer temperature and the thin film coating on the wafer surface. We are able to btain the pr...
متن کاملanalysis of performance characteristics of two-lobe journal bearing with micropolar lubricant
in this paper, static performance characteristics for a finite lenght two-lobe journal bearing lubricated with micropolar fluid is studied. using finite element method, steady-state film pressure is obtained by solving modified reynolds equation, based on micropolar lubrication theory. with the help of film pressure in bearing, the static performance characteristics in terms of load carrying ca...
متن کاملFundamentals of Fluid Film Journal Bearing Operation and Modeling
Widely used in turbomachinery, the fluid film journal bearing is critical to a machine’s overall reliability level. Their design complexity and application severity continue to increase making it challenging for the plant machinery engineer to evaluate their reliability. This tutorial provides practical knowledge on their basic operation and what physical effects should be included in modeling ...
متن کاملFilm thickness distribution in magnetron sputtering
Of crucial importance to the thin film process engineer is an understanding of the parameters which affect the film thickness distributions which may be obtained from magnetron sources. This paper describes how variations in source design, target erosion and source-to-substrate distance affect observed uniformities from a magnetron source. A simple method of simulating magnetron sources using t...
