Russ Hobbie and I discuss the Reynolds number in Section 1.18 (Turbulant Flow and the Reynolds Number) of the 4th edition of Intermediate Physics for Medicine and Biology. The importance of turbulence (nonlarminar) flow is determined by a dimensionless number characteristic of the system called the Reynolds number

Get priceDec 07, 2017Reynolds number is a basic principle of fluid mechanics and plays a prominent role in industrial mixing. The Reynolds number concept was first introduced over 150 years ago by George Gabriel Stokes, a mathematics professor at Cambridge.

Get priceBar-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).

Get priceNov 17, 2015Take a round, cylinder cooling channel design for example, a fully-developed turbulence will occur when the Reynolds number reaches 4000 or higher. Reynolds number indeed provides a significant insight for users to understand the flow patterns inside the cooling channels and serves as a great reference to evaluate the cooling efficiency as well.

Get priceJul 09, 2013Terminal Velocity. The key variable in gravity separation calculations is the terminal velocity of the settling particle. The terminal velocity indicates whether a heavy particle will separate against an upward fluid flow or whether a system has sufficient residence time for a particle to settle.

Get priceTurbulent or laminar flow is determined by the dimensionless Reynolds Number which is important when analyzing fluid flow where there is a substantial velocity gradient (i.e. shear).The Reynolds number indicates the relative significance of the viscous effect compared to the inertia effect and the number is proportional to the inertial force divided by the viscous force.

Get priceThe degree of roughness was designated as the ratio of the sand grain diameter to the pipe diameter ( /D). The relationship between the friction factor and Reynolds number can be determined for every relative roughness. From these relationships, it is apparent that for rough pipes the roughness is more important than the Reynolds number in

Get priceSand casting. The most versatile method for producing aluminum products is sand casting. The process starts with a pattern that is a replica of the finished casting. Virtually any pattern can be pressed into a fine sand mixture to form the mold into which the aluminum is poured.

Get priceThe 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
