Some Features of Combined Convection Mass Transfer for Pulsating Fluid Flow in a Pipe

Abstract

Mass transfer under the combined convection condition in a vibrating flow imposed on a steady fluid flow in a pipe was studied by using an electrochemical method. We found that the mass transfer for pulsating flow can be expressed by the following 3rd- and 4th-power relations in the present experimental range.
k_fv³=k_f³+k_v³
130<Ud/ν<1600, 170<d²ω/ν<1600, 500<aωd/ν<1000
k_fv⁴=k_f⁴+k_v⁴
330<Ud/ν<1600, 1600<d²ω/ν<2100, 1000<aωd/ν<3000
where subscript f means steady fluid flow, v vibrating flow and fv pulsating flow.
