In combustion engineering and explosion studies, the Markstein number characterizes the effect of local heat release of a propagating flame on variations in the surface topology along the flame and the associated local flame front curvature. The dimensionless Markstein number is defined as: where is the Markstein length, and is the characteristic laminar flame thickness. The larger the Markstein length, the greater the effect of curvature on localised burning velocity. It is named after (1911—2011), who showed that thermal diffusion stabilized the curved flame front and proposed a relation between the critical wavelength for stability of the flame front, called the Markstein length, and the thermal thickness of the flame. Phenomenological Markstein numbers with respect to the combustion products are obtained by means of the comparison between the measurements of the flame radii as a function of time and the results of the analytical integration of the linear relation between the flame speed and either flame stretch rate or flame curvature. The burning velocity is obtained at zero stretch, and the effect of the flame stretch acting upon it is expressed by a Markstein length. Because both flame curvature and aerodynamic strain contribute to the flame stretch rate, there is a Markstein number associated with each of these components. (Wikipedia).
Hitler and the Hohenzollerns - The Kaiser's Family & the Nazis
During the Nazi period, the former Imperial Family of Kaiser Wilhelm II maintained a strange relationship with Hitler, hoping that he would re-instate one of them to the post of Emperor. Dr. Mark Felton FRHistS, FRSA, is a well-known British historian, the author of 22 non-fiction books
