A physical interpretation of von Karman's constant based on asymptotic considerations - A new value

摘要

The asymptotic profiles of a viscous flow and an inviscid turbulent flow are matched by the appropriate choice of the only free parameter, the von Karman constant kappa. The matching result is kappa = exp(-1) - 0.3678.... This value is supported by recent experimental evidence from measurements at the very large Reynolds numbers required for the determination of the (asymptotic) value of von Karman's constant.
