Design of a capillary viscometer with numerical and computational methods
A high temperature and shear rate capillary viscometer has been designed, constructed and recently commissioned. This device will be used to measure the viscosity of semi-solid metals under the high temperature and shear rate conditions, similar to those found in industry. Design criteria for the device included a requirement for a highly controllable temperature (±1oC) up to 650oC, capability ...
متن کاملAutomated measurement of plasma viscosity by capillary viscometer.
Plasma viscosity has several advantages over the erythrocyte sedimentation rate as a measurement of an acute phase response of more than 24 hours' duration. A new capillary viscometer (Coulter Viscometer II), which gives an automated measurement of plasma viscosity, was compared with the selected manual method (Harkness viscometer) of the International Committee for Standardization in Haematolo...
متن کاملA Coaxial Cylinder Type Rotational Viscometer- Design and Optimization
The history of viscosity measurements is outspread and is believed to date back to when people began measuring the viscosities of engine oils with the advent of the automobile industry [1]. A rotational viscometer is one which can be used to measure viscosity at different temperature. In this treatise, a coaxial cylinder type rotational viscometer (CCTRV) has been designed, constructed and comp...
متن کاملKey words: capillary-viscometer, viscosity function, Newton-Raphson procedure, genetic algorithm
This contribution gives an overview about new procedures for the parameter identification for the material characterisation of rubber blends. They are based on a Newton-Raphson procedure and a genetic algorithm. As basis serves an experimental investigation of the viscous properties of rubber blends by means of a capillary-viscometer. Because of simultaneous consideration of wall slippage, temp...
متن کاملAn Optical Fiber Viscometer Based on Long-Period Fiber Grating Technology and Capillary Tube Mechanism
This work addresses the development and assessment of a fiber optical viscometer using a simple and low-cost long-period fiber grating (LPFG) level sensor and a capillary tube mechanism. Previous studies of optical viscosity sensors were conducted by using different optical sensing methods. The proposed optical viscometer consists of an LPFG sensor, a temperature-controlled chamber, and a cone-...
