✦ Synopsis

We present a chemical-reaction model to describe the Mexican wave (La Ola) in football stadia. The spectator's action is described in terms of chemical reactions. The model is governed by three reaction rates k1; k2; and k3. We study the nonlinear waves on one-and two-dimensional lattices. The Mexican wave is formulated as a clockwise forwardly propagating wave. Waves are growing or disappear, depending on the values of reaction rates. In the speciΓΏc case of k1 = k2 = k3 = 1, the nonlinear-wave equation produces a propagating pulse like soliton.

A continuous shock wave reactor with a single instrumented shock tube was built, based on the concept of a disc rotating within a concentric ring about a shaft perpendicular to the disc's plane. The shock tube is a small tube having a square cross section, which is also a diameter of the disc. The r
