WebJun 17, 2016 · I am trying to find out some non-dimensional parameters such as Reynolds no, Grashof no and Rayleigh number for my test case. I am trying to model a flow through a glass tube through which water is flowing. I have used Boussinesq approximation for the analysis (natural convection taking place inside the tube). WebSep 1, 2002 · Grashof's (crank) defectIf no link in the mechanism is capable of rotating fully, the linkage is said to have Grashof defect. This happens when the shortest link is neither a driving link nor a ground link [162]. For example: the triple rocker mechanism in which all the links except the ground link are the rockers. 4.3.

WebThe role played by Reynolds number in forced convection is played by the Grashof number in natural convection. The critical Grashof number is observed to be about 109 for vertical plates. Thus, the flow regime on a vertical plate becomes turbulent at Grashof number greater than 109.
