reynolds number in sand casting

Magnetic Reynolds number Wikipedia

The magnetic Reynolds number (R m) is the magnetic analogue of the Reynolds number, a fundamental dimensionless group that occurs in magnetohydrodynamics. It gives an estimate of the relative effects of advection or induction of a magnetic field by the motion of a conducting medium, often a fluid, to magnetic diffusion .

Exam Problem #25 (The Reynolds Number)

Jun 27, 2014The Reynolds Number (Re) is a dimensionless number that is the ratio of inertia forces to viscous forces. When this number is less than 2,000, the flow is laminar. When the number is greater than 4,000 the flow is considered turbulent. I The Reynolds number is a dimensionless number. This statement is true.

Bar-like sand mould tilted angle reduced free surface fluctuations. The primary and secondary reflected wave heights decreased with the scaling of Re 0.8 and Re 0.55, respectively.These heights were reduced by 54% and 51% when θ was increased from 0 to 5. A larger tilted angle was found to generate an air cavity in the cast, the size of which was observed to vary with Reynolds number (Re).

Reynolds number Wiki Everipedia

The Reynolds number (Re) is an important dimensionless quantity in fluid mechanics used to help predict flow patterns in different fluid flow situations. At low Reynolds numbers flow tends to be dominated by laminar (sheet-like) flow, but at high Reynolds numbers turbulence results from differences in the fluid's speed and direction, which may sometimes intersect or even move counter to
