FIELD: process engineering. ^ SUBSTANCE: this invention covers acoustic device (and method) facilitating interaction between solid body and gas that envelopes that body or at least staying in contact with said body surface. Acoustic device facilitating interaction between solid body (100) and gas (500) that envelopes that body or at least staying in contact with said body surface (204), comprises sound or high-intensity ultrasound source (301) to act on surface (204), outer part (305) and inner part (306) that defines passage (303), hole (302), chamber (304) arranged inner part (306). Note here that said acoustic source (301) serves to receive compressed gas and force it into hole (302), wherefrom said gas is forced into nozzle towards chamber (304). Note here that sound or high-intensity ultrasound is applied directly to gas (500) to propagate said sound or ultrasound to surface (204) of body (100), to reduce and/or minimise laminar sublayer (203) on surface (204) of body (100). Note that sound or ultrasound intensity makes 140 dB or higher. ^ EFFECT: decrease in laminar sublayer causes increase in efficiency of heat exchange and/or rate of said catalytic process and/or that of gas exchange. ^ 15 cl, 12 dwg |
