This invention relates to viscous fluid coupling devices which serve as a drive for the radiator cooling fan of a vehicle engine, and more particularly, to such coupling devices which control the drive for the fan in response to ambient air temperature of the engine. ...
Furthermore, it would be desirable to provide an additive which does not affect the other physical properties of the slurry, such as the electrical conductivity and the surface charge of the particle surface in an unacceptable way. It would also be desirable to provide an aqueous slurry of a ...
Introduction The performance of an engineering systems gets degraded due to the presence of irreversibilities such as friction, mixing of fluids, non-quasi-static compression or expansion, chemical reactions, heat flow because of a temperature gradient, and unrestrained expansion (such as explosion)....
