Improvement of Burden and Gas Distribution in Blast Furnace Based on Full Scale Model Experiments

It is inevitable that the wake affects on the braking force of tugboat towing in the stern of a ship. In order to understand the effect of ship-tugboat interaction on the braking force of tugboat, we have to consider two interference components, namely on the tugboat’s braking force in ships wake and on ship’s hull resistance. First, the interference component on the tugboat’s braking force is predicted considering the scale effect of ship’s wake velocity distribution, and using the braking force coefficient of tugboat-self in the uniform flow[1]. Then the interference component on ship’s hull resistance is also estimated under an assumption, which this component in full scale ship is in proportion to Schlichting’s frictional resistance as the component obtained in scale model experiments being a constant. Finally, the effective braking force for full scale tugboats was predicted by using the experiment data and the assumptions mentioned above.

The development of a family of low-maintenance, reusable crash cushions that employ energy dissipaters made of high-molecular-weight–high-density polyethylene is described. This “smart” energy dissipating thermoplastic is self-restorative and reusable and possesses excellent hysteresis characteristics. The design process involved quasi-static and impact scale model experiments, finite-element modeling, and a full-scale crash testing program conducted according to the guidelines of NCHRP Report 350. A treatment of all of these design components is presented. It is demonstrated that scale model experiments and finite-element modeling are cost-effective tools whose employment can minimize the number of costly full-scale crash tests required to qualify devices as acceptable for use on the National Highway System.

The Stability

The full-scale model test is used to study the stability and deformation control of reinforced sloped embankments on mountain slope foundation. According to practical experience in the expressway construction in the mountain region, two full scale model experiments were carried out in laboratory. One model is reinforced by geogrid and the other is un-reinforced in the embankments. The design of the model, test data and analysis methods are emphatically introduced. During the experiments, some key test data were monitored, such as the vertical and horizonal displacements distribution of slope, the vertical displacement on the top of the embank, the internal stress and displacement distribution, the form and position of the slip curve surface in the two embankments. Comparing experiment of reinforced with un-reinforced, it shows that the lateral displacement of embankments of the former is smaller and the stability of embankments is higher than that of the latter. The model experiment results can give reference for the construction of China's western mountain highway.

Mesh Convergence

In this paper, a commercial CFD code, ANSYS-Fluent has been used to investigate the effect of mesh number generated in the computed domain on the CFD aerodynamic performances of a container ship. A full-scale model of the 1200TEU container ship has been chosen as a reference model in the computation. Five different mesh numbers for the same dimension domain have been used and the CFD aerodynamic performances of the above water surface hull of the ship have been shown. The obtained CFD results show a remarkable effect of mesh number on aerodynamic performances of the ship and the mesh convergence has been found. The study is an evidence to prove that the mesh number has affected the CFD results in general and the accuracy of the CFD aerodynamic performances in particular.
