G0210103 A numerical simulation of splash which laser induced liquid jet makes.

Abstract

Laser Induced Liquid Jet (LILJ) is investigated about novel medical treatment device. LILJ uses liquid on dissection or removal of tissue with preserved vessel. Medical anxieties are dissemination and droplet infection with splash interacting between tissue and liquid. In this study, numerical simulation was attempted that estimation of range on droplet with worst case. And, LILJ and high-speed camera were used for validation of result on numerical simulation. Numerical simulation was not convergence with real boundary conditions. Experimental result clarified that droplet was not occurred when nozzle tip was in liquid on the target surface.
