Effect of volume fraction and particle size on wall slip in flow of polymeric suspensions
Gulmus, SA; Yılmazer, Ülkü (Wiley, 2005-10-05)
For especially highly concentrated suspensions, slip at the wall is the controlling phenomenon of their rheological behavior. Upon correction for slip at the wall, concentrated suspensions were observed to have non-Newtonian behavior. In this study, to determine the true rheological behavior of model concentrated suspensions, "multiple gap separation method" was applied using a parallel-disk rheometer. The model suspensions studied were polymethyl methacrylate particles having average particle sizes, in the...
Effect of sugar type and water content on the physical properties of marshmallows
Kırtıl, Emrah; Öztop, Halil Mecit (null; 2015-08-10)
Marshmallow is an aerated confectionery product with a characteristic foamy structure created when air and moisture is incorporated into a sugar mixture containing gelatin. The air entrapped in the marshmallow matrix is responsible for its fluffy texture. Moisture absorption/loss of marshmallows during storage and transportation is one of the most important quality defects that make the product unacceptable. In this study, marshmallows prepared at different compositions were examined. Sugar type, concentrat...

Effect of particle size and heating rate on the pyrolysis of Silopi asphaltite
Altun, Naci Emre; Kök, Mustafa Verşan (Elsevier BV, 2003-5)
This study comprises the effect of particle size and heating rate on the pyrolysis of Silopi, Turkey asphaltite by non-isothermal thermogravimetry. The TG/DTG experiments were performed at five different heating rates with three different size fractions from ambient up to 900 degreesC in nitrogen atmosphere. The pyrolysis characteristics of the samples were analyzed using TG/DTG curves. Also, the pyrolysis kinetics of the samples were determined using the Arrhenius type kinetic model and ASTM methods. Resul...
