Abstract

Transient natural convection in a repetitive geometry, periodically heated from below with a temperature that varies sinusoidally with time, is studied numerically. Parameters of the problem are the Rayleigh number, the dimensionless amplitude and period of the variable input temperature. By considering air (Pr = 0. 72) as a working fluid and maintaining the geometrical parameters constant, different routes leading to chaos are identified by progressively varying the influencing parameters.
