Reynolds Number

Reynolds Number

Reynolds Number

(OP)


                          I am wondering how you calculate the Reynolds Number, Re, for wire moving in a fluid. What
                          characteristic dimension do you use; and what criteria do you use to determine a turbulent state?

                                My approach would be to use

                           Re = vD/viscosity(k)
                           v = velocity of wire D = diameter of wire
                           viscosity(k) = kinematic viscosity
                          And to use the criteria for flow over a flat plate. Does this make any sense?

                          Thank You

RE: Reynolds Number

hello,
  There is two type for determining Re:
 1. condition:The STATIC object in the  streaming fluid Or
              The moving object in the static fluid
  method: Re=V.D/v that D means diameter of object &V means velocity of object or fluid
 Aim: study on sedimentation of object
 2. condition :the streaming fluid
 method:Re=V.D/v that D means diameter of canal& V means velocity of fluid
 Aim:study on condition of fluid.
  I wish this help you.
