...Sanjivan Manoharan; Anirudh M. Deodhar; Raj M. Manglik; Milind A. Jog The growth dynamics of isolated gas bubbles from a submerged capillary-tube orifice in a pool of an aqueous surfactant (sodium dodecyl sulfate or SDS) solution is computationally investigated. The governing equations...

... the effect of surfactant concentration in water jet cooling, and its applicability in the study of ultrafast cooling (UFC) of a hot steel plate. The initial temperature of the plate, before the cooling starts, is kept at 900 °C which is usually observed as the “finish rolling temperature (FRT)” in the hot...

...Minh Do-Quang; Gustav Amberg; Claes-Ove Pettersson This paper presents a comprehensive three-dimensional, time-dependent model for simulating the adsorption kinetics and the redistribution of surfactants at the surface and in the bulk of a weld pool. A physicochemical approach that was included...

...Wael I. A. Aly; Hideo Inaba; Naoto Haruki; Akihiko Horibe Flow drag and heat transfer reduction phenomena of non-ionic aqueous surfactant solutions flowing in helical and straight pipes have been experimentally investigated at surfactant solution concentration range of 250 - 5000 ppm...

...Paul L. Sears; Libing Yang Heat transfer coefficients were measured for a solution of surfactant drag-reducing additive in the entrance region of a uniformly heated horizontal cylindrical pipe with Reynolds numbers from 25,000 to 140,000 and temperatures from 30 to 70 ° C . In the absence...
