Circular crested waves in thermoelastic plates bordered with viscous liquid

Sharma J. N., Sharma P. K., Pathania S.

International Journal of Applied Mechanics and Engineering

2012

Vol. 17, no. 2

513-534

In this paper the propagation of thermoelastic waves in a homogeneous, transversely isotropic, thermally conducting elastic plate bordered with layers (or half-spaces) of a viscous liquid on both sides is investigated in the context of non classical theories of thermoelasticity. Complex secular equations for symmetric and antisymmetric wave motion of the circular plate, in completely separate terms, are derived. The regions of the secular equation, waves of short and long wavelength are also discussed. Finally, in order to illustrate the analytical results, the numerical solution is carried out for a transversely isotropic plate of cobalt material bordered with water by using the functional iteration method. The results are deduced and compared with the existing ones in relevant publications available in the literature at various stages of this work.

Modeling of mixing time for ribbon impellers

Szulc K., Kuncewicz C.

Inżynieria Chemiczna i Procesowa

2006

T. 27, z. 2

567-577

Velocity distributions of liquid in a tank equipped with ribbon impellers during mixing of highly viscous liąuids have been experimentally examined. The values of secondary circulation and mixing times were determined. Experimental results were compared with the results obtained from the mathematical model proposed in an earlier study. The effect of geometrical parameters of the impeller on mixing time was also determined.

Wykonano badania doświadczalne rozkładów prędkości cieczy o dużej lepkości w mieszalniku podczas jej mieszania mieszadłami wstęgowymi. Określono wartości cyrkulacji wtórnej oraz czasu zmieszania. Wyniki badań porównano z wynikami uzyskanymi z rozwiązania zaproponowanego wcześniej modelu matematycznego. Określono zależności czasu zmieszania od parametrów geometrycznych mieszadła.
