| Research Abstract |
On producing liquid micro-capsules by using a compound liquid jet which consists of core and annular phases, effects of non-Newtonian viscosity in a polymer liquid and Marangoni effects due to locally varying concentration of a surfactant are investigated. In particular, disintegrations of the annular phase due to the ballooning phenomena appearing in a low Reynolds number region become worse when the viscosity is pseudo-plastic comparing with Newtonian and dilatant, except for sufficiently low Weber numbers and inner surface tension.
