A Galerkin finite element-unrestrained modal synthesis method is proposed for predictingthe fluid-structure coupling natural vibration modes and responses of hydrodynamic pressu-res free liquid surface displacements and container deformations to excitations such as earth-quakes in a liquid filled elastic container. It has been applied in particular to treatmentof the hydroelastic problems of liquid containers of revolution. Improvement has been madein axisymmetric finite element modelling to overcome the drawbacks of existing semi-analy-tical finite element models for analyzing axisymmetric potential problems. All dynamicfluid-structure coupling effects have been taken into account. Numerical results show goodagreement with experimental ones and considerable reduction in computational workload.The present method is especially efficient in the hydroelastic analysis of a container filledwith different liquids or the same liquid to different depths.

In order to predict heat transfer characteristics of long tube vertical failing film evaporators, a new model for flow and heat transfer in turbulent film flow is presented based on eddy viscosity profiles suggested by Levich for absorptioa of gases into films. The model considers the effects of interracial shear and the damping of the eddy diffusivity near the free liquid/gas interface due to surface tension. The differential equations of the model are solved numerically. From the velocity and temperature distributions, liquid film thickness and heat trensfer coefficient are calculated. An experimental study of heat transfer in a long tube vertical film evaporator has been made at conditions used in industry. Comparison of predicted and experimental data shows that they are in satisfactory agreement. For the design of falling film evaporators, a computer program has been developed, which enables to evaluate wall temperature, film thickness, heat transfer coefficient, etc.

Under microgravity condition, the main problem about liquid propellant management is to control the position of the liquid in the tank,so that the gas-free liquid propellant transfered to the engine is gas-free. For a kind of pear-shaped tank used in a spinnig stabilization satellite,a drop tower test was performed with ionless water as test media in a transparent plexiglass scale model. The interface shape between gas and liquid at the time after satellite saperating from the launcher and before the saellite spinning, the gas ingestion phenomena during liquid draining and the critical volume of the residue liquid when gas ingestion begin, to happen are determined by tests.A kind of large scale surface tension tank will be used in long life time satellite. Some fluid flow characters concerned will be tested under microgravity condition such as equilibrium position of the gas-liquid interface,expulsion efficiency,pressure loss and liquid slosh etc. to verify the design option.
