Natural convection in an annular space provided with metal foam fins attached to the inner cylinder is studied numerically. The made of copper were inserted different axial sections three each section. temperature kept constant while outer surface adiabatic. thickness effect pipe wall was considered. Naiver Stokes equation Boussinesq approximation used for fluid regime Brinkman-Forchheimer Darc...

Inspired by a line dancing club in Stoke-on-Trent, and drawing principally on cultural theorist Raymond Williams, this article makes the case for appreciating ways that practices age change over time. This group of dancers held deep, long, collective familiarity with their practice, through intimacy an idiosyncratic attitude to mistakes emerged. Taking these mistakes, collectively recast as ‘va...

This article reports on a research project which investigated early years practitioners’ perspectives of best practice and effective provision in relation to the Understanding World area learning Early Years Foundation Stage. focuses ‘People Communities’, ‘The World’, ‘Technology’. A mixed-methods approach utilising an online survey semi-structured interviews generated data from practitioners l...

in this paper the heating process in a box annealing unit is simulated and the effect of various parameters involved in the process is examined. for this purpose, the full naiver-stokes equations along with the standard k- turbulence model are solved in the fluid region using the finite volume approach. in the solid area the conduction heat transfer equation is employed using approporate surfac...
