Abstract The effect of aspect ratio and baffle shape on natural convection patterns in a U-shaped cavity filled with CuO water-based nanofluid is examined detail, T-shaped attached to the cold wall. To solve coupled continuity, momentum, energy equations, finite volume method used, pressure–velocity coupling iteratively solved SIMPLE algorithm. study investigates impact Rayleigh number (10 4 –1...

The change in shape of the C. elegans embryo from an ovoid ball of cells into a worm-shaped larva is driven by three events within the cells of the hypodermis (epidermis): (1) intercalation of two rows of dorsal cells, (2) enclosure of the ventral surface by hypodermis, and (3) elongation of the embryo. While the behavior of the hypodermal cells involved in each of these processes differs drama...

This study simulates natural convection flow resulting from heat partitions in an H-shaped enclosure filled with a nanofluid using incompressible smoothed particle hydrodynamics (ISPH) method. The right area of the is saturated non-Darcy porous media. center variable walls are kept at high-temperature Th. left and positioned low temperature Tc other adiabatic. In ISPH method, source term pressu...

Non-human animals and human children can make use of the geometric shape of an environment for spatial reorientation and in some circumstances reliance on purely geometric information (metric properties of surfaces and sense) can overcome the use of local featural cues. Little is known as to whether the use of geometric information is in some way reliant on past experience or, as would likely b...
