What is the expression for the expected thickness of a turbulent
plane shear layer? What is the constant of proportionality? Does
this seem in reasonable agreement with experiments?
What is the expression for the expected diameter of a turbulent
jet? What is the constant of proportionality? Does this seem in
reasonable agreement with experiments?
The book claims that two-dimensional and round turbulent jets
grow in size at the same rate, but that their velocity decays at a
different rate. Does that make sense? Why would one be the same
and the other different?
Would the similarity arguments made in class for a turbulent jet
hold for a jet in a coflowing stream (like a jet coming out of a jet
engine of a plane in flight)? If not, why not?
