The Zeldovich number, often denoted as \\( Z \\), is a dimensionless quantity used in the field of combustion and thermal analysis. It is particularly relevant in the study of gas-phase chemical reactions and the dynamics of combustion processes. The Zeldovich number is defined as the ratio of the characteristic time scale of heat release to the characteristic time scale of thermal diffusion.
