Of particular interest is the verification\n\tof scaling laws relating the frequency f to given quantities, namely\n\td, the height of the jet, w, the stand�off distance and the velocity\n\tof the jet. We conclude that the Strouhal number Sd is related to\n\tthe geometrical quantities through Sd = C � (d / w)n with n � 1,\n\tin contrast to some analytical treatments of the problem. The constant\n\tC of the experiment agrees within 13�15\\% with the result of the\n\tnumerical treatment. Only a weak dependence on the Reynolds number\n\twith respect to d is observed. In general, a very good agreement\n\tof the experimental and the numerical simulations is found.",

Assuming\n\twell-posedness of the continuous problem and requiring only basic\n\tproperties of the adaptive algorithm, we prove convergence of the\n\tsequence of discrete solutions to the true one. The proof is based\n\ton the ideas by Morin, Siebert and Veeser but replaces local efficiency\n\tof the estimator by a local density property of the adaptively generated\n\tfinite-element spaces. As a result, estimators without a discrete\n\tlower bound are also included in our theory.
