|In the present study, the effect of the heating pipe profile on natural convection in a two –phase |
fluid inside a cavity have been investigated. This geometries has been simulated with the Lattice
Boltzmann Method based on D2Q9 model for analyzing stream lines, dimensionless velocity field of
fluid flow, solid particles volume fraction, temperature arrangement and Nusselt number. These
parameters have been investigated in 3 cases of the cavity. The results signified by changing the
geometry from a horizontal ellipse to a circular one and a vertical ellipse, the Maximum volume
fraction of solid particles decreased. Also, by changing the geometry from a horizontal ellipse to a
circular and vertical ellipse, larger velocity vectors have been formed around the geometry. The
Nusselt number variations of circular and vertical ellipse geometries in the lower half have a similar
behavior. The Nusselt number variation of horizontal ellipse geometry in the lower half is
insignificant. Also, the Nusselt number of the circular geometry in the upper half is larger and
uniform compared to the other two geometries. The highest average Nusselt number belongs to
circular, vertical and horizontal ellipse geometries respectively.
