Mass on a spring map for the dripping faucet at low flow rates.
An improved discrete map for the mass-on-a-spring model for the dripping faucet is used to reproduce the evolution of experimental dripping spectra at low flow rates. If an inverse dependence of drop mass on flow rate is supposed, a repeated evolution from period 1 to chaos is obtained. A comparison between discrete relaxation oscillator attractors and dissipative type-web map attractors is carried out. It is found that a dissipative web map accounts for some characteristics of the relaxation oscillator map, thus giving further tools for investigation.
