High temperature high shear viscosity
WebThe CANNON® High-Temperature High-Shear Capillary Viscometer (HTHS Series II) is designed to determine the viscosity of engine oils and other oils under conditions of high shear at high temperatures. The HTHS is capable of testing at 1.4 x 106s-1 at 150°C and meets all precision specifications of ASTM D 5481 and SAE J300. WebShear-thickening fluids are sometimes called dilatant fluids, because many are high-concentration slurries that must expand (dilate) at the particle level in order to flow. Time-dependent non-Newtonian fluids change appar-ent viscosity not only with shear rate, but also during and following the applied shear. Time-dependent, shear-thinning
