Experimental and numerical study on air cores for cylindrical tank draining
Il Seouk Park,Chang Hyun Sohn +1 more
TL;DR: In this paper, the drain time, the change in the free surface shape, velocity field, and vorticity distributions were numerically and experimentally investigated, and the results were in good agreement with each other with respect to drain time.

Eccentric Drain Port to Prevent Vortexing During Draining from Cylindrical Tanks
TL;DR: In this paper, it was shown that even with initial rotation given to the liquid column, vortexing can be prevented by using eccentric drain holes, and this phenomenon has practical relevance in the fuel feed system in space vehicles and rockets.
Journal ArticleDOI
Numerical analysis of vortex core phenomenon during draining from cylinder tank for various initial swirling speeds and various tank and drain port sizes
TL;DR: In this paper, the authors investigated the time at which the vortex core is initially generated using different values of tank diameter, drain port diameter, and initial tank rotational speeds, and solved the momentum conservation equation in the circumferential direction in the two-dimensional mesh system.
Journal ArticleDOI
Draining of liquid from tanks of square or rectangular cross sections
TL;DR: In this article, industry provided data for three nozzle combinations and the switch time for each of these three engine designs was optimized, and the resulting best points are shown in Fig. 4.

Axisymmetric draining of a cylindrical tank with a free surface
TL;DR: In this article, a fully cubic-spline nonlinear axisymmetric boundary-integral method with the built-in boundary conditions was used to reduce the numerical errors at the intersection lines where the tank wall and the density interfaces meet.

Effects of tripropellant engines on earth-to-orbit vehicles
TL;DR: In this paper, the effects of tripropellant engines on earth-to-orbit vehicles were examined in terms of their impact on engine configurations and launch capabilities, with a dual-expander engine being identified as the most fuel dry mass reduction for a given payload.
