摘要:
When a horizontal cw laser beam is suddenly turned on in a quiescent isothermal fluid there is a delay timet*during which thermal blooming is governed by absorption of radiation and thermal conduction. Fort≳t*, free convection becomes a significant factor.t*is determined by an approximate quasisteady hydrodynamic stability analysis and is compared with existing experimental data.
