Through the analysis and calculation for the test data of both real ship and model ship, the difference between the method of inland ship sailing resistance calculation and that of mountainous river and hill-stream was discussed. And also, the formula for calculating the fleet of barges sailing resistance were proposed.
On the basis of DPIV(PIV)principle,the motion of model ship is reflected from fracing the displacement of light source on the screen. Therefore,it may eliminate the bound to the motion of model-ship due to loading the instruments on the model-ship itself.
The interaction of the thruster generated jets with the flow near a ship hull model is studied at low flow velocities.
A hybrid ship hull model made with a steel truss and composite sandwich panels was tested and analyzed with the goal of gaining insight into how well this structural concept holds up after major damage.
For this lab, the class will test a series 60 ship hull model in the MIT Tow tank using their imarine web-based laboratory controls.
We first investigated the ease of passage through a microcatheter in a realistic cerebral vessel model.
The long J-shaped coils were easily advanced and retrieved through a microcatheter in a tortuous vessel model.
The concept was analyzed by numerical calculations based on the Gilmore model of cavitation dynamics and by high-speed photography of the effects of single and double pulses performed with a silicone tube as vessel model.
The role of fructose-1, 6-diphosphate in cell migration and proliferation in an in vitro xenograft blood vessel model of vascula
The approach is based on the application of a general blood vessel model and on anatomical models which take into account the normal variations of the coronary artery structure.
本文在介绍利用环流理论方法设计推进器之先,把环流的基本原理以浅近的学理予以阐明,使具有推进器的基础学识的读者,不需参考其他书籍,能够领会。作者指出环流理论设计的优点,亦指出其存在的问题。在文中介绍了四种设计方法:(一)荷兰船模试验池的方法;(二)娄勃氏(Lerbs)的方法;(三)赫尔(Hill)的方法;(四)爱克赫脱及马根(Eckhardt and Morgan)的方法;除说明设计的步骤外,还指出各方法中的特点,以增进我们对于推进器理论的理解。这四种设计方法是适宜于在船舶设计部门中运用的。希望这篇总结性的文章能对我们的造船设计工程师们有所帮助。为了避免文章过于冗长,没有在本文中举出有数字的实例来作说明,有待将来另作文继续补充。
