The article deals with experimental studies of how capillary fluid drainage systems (CFDS) of fuel tanks function when the liquid fuel component flows around their phase separators. We present a theoretical model describing this process. Based on the analysis conducted, we used a flow loop facility to simulate actual operation conditions, for example, the liquid component motion over the fuel tank volume creating extra dynamic load on the CFDS. Comparative analysis of experimental data and previously obtained theoretical investigation results concerning the process of the liquid component flowing around the cylindrical phase separator grates showed good convergence of results
