Journal ArticleDOI
Evolution of rheological properties of highly concentrated emulsions with aging —Emulsion-to-suspension transition
Irina Masalova,Alexander Ya. Malkin,Ernst Ferg,Ellina Kharatiyan,Michael Taylor,Rainer Haldenwang +5 more
TL;DR: In this article, the effect of aging on the rheological properties and physical structure of highly concentrated water-in-oil emulsions with dispersed phase of 82-90v% is the subject of this study.
Journal ArticleDOI
Optimisation of pulsed ultrasonic velocimetry system and transducer technology for industrial applications
TL;DR: In this paper, a specially designed delay line transducer was designed and evaluated to increase the accuracy of velocity data close to wall interfaces and solve previous problems by measuring physical properties of the ultrasonic beam and implementing a newly developed deconvolution procedure.
Journal ArticleDOI
Characterisation of winery wastewater from continuous flow settling basins and waste stabilisation ponds over the course of 1 year: implications for biological wastewater treatment and land application
TL;DR: It is recommended that if land requirements can be met, winery effluent should be stored in ponds prior to treatment, and it is possible that bacterial and algal nitrogen fixation in such systems may enhance biological wastewater treatment by natural nitrogen supplementation.
Journal ArticleDOI
Experimental procedure and database for non-Newtonian open channel flow
Rainer Haldenwang,Paul Slatter +1 more
TL;DR: Haldenwang et al. as mentioned in this paper used a large experimental database for non-Newtonian open channel flow and tested three rectangular tilting flumes of different widths varying from 75 to 300 mm on three fluids: bentonite and kaolin suspensions and carboxymethylcellu.
Journal ArticleDOI
Friction factor-Reynolds number relationship for laminar flow of non-Newtonian fluids in open channels of different cross-sectional shapes
TL;DR: The effect of channel shape on the friction factor-Reynolds number relationship for laminar, open channel flow of three non-Newtonian fluids was investigated and the K values were found to be in line with those reported by Straub et al. (1958) and Chow (1959).
