NANO-SIZED PARTICLE GENERATING DEVICE FOR CONTROL OF BOUNDARY LAYER OF SUBMERGED BODY

摘要

PURPOSE: A nanoparticle manufacturing apparatus for controlling boundary layer of submerged body is provided to bring monodispersed nano particles in bubble into the boundary layer of the submerged body by forming bubbles on surface of the submerged body. CONSTITUTION: A nanoparticle manufacturing apparatus for controlling boundary layer of submerged body comprises an atomizer(1) in which NaCl or DEHS solution is sprayed in order to produce polydispersed nanoparticles, a diffusion dryer(2) which eliminates moisture of the polydispersed nanoparticles; a neutralizer(3) which electric charging the moisture removed polydispersed nanoparticles to positive charge or negative charge; polydispersed nanoparticles that are moisture removed, and a DMA(differential mobility analyzer)(4) which brings the monodispersed nanoparticles into a submerged body(6) by applying voltage to polydispersed nanoparticles and producing monodispersed nanoparticles.
