What electronic measuring instruments with high accuracy for measuring the viscosity of fuels and lubricants are currently on the market?

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

Dear Avaz Yangiboyev , the devices from Anton Paar GmbH might be what you are looking for, e.g. https://www.anton-paar.com/corp-en/products/group/viscometer/

Hi Avaz Yangiboyev

Yes you can use a rotational rheometer like this to accurately characterize viscosity of most materials including fuel (with a solvent trap cover). Kinexus Range rotational rheometers - NETZSCH Analyzing & Testing (netzsch-thermal-analysis.com) which allows control over the temperature, shear rate and other factors:

Other more manual methods include the Stonybrook Scientific falling needle viscometer: Stony Brook Scientific, Ltd. Falling Controlled Needle Viscometer http://www.stonybrooksci.com/Products/ProductsFallingControlledNeedleViscometer.htm

Best regards,

Phil
