This paper approaches the behavior of the critical suspension ofparticles in a propeller loop reactor (PLR), and mainly attacks atthe influences of the type and the diameter of propeller, the diameterof draft tube, the installation, height of propeller over the bottom ofthe reactor,the particle concentration in liquid and the density ofsolid particles upon the critical rotative velocity when particles suspendin liquid in the PLR.It is discovered that the rotative velocity willreduce with the installation...

This paper approaches the behavior of the critical suspension ofparticles in a propeller loop reactor (PLR), and mainly attacks atthe influences of the type and the diameter of propeller, the diameterof draft tube, the installation, height of propeller over the bottom ofthe reactor,the particle concentration in liquid and the density ofsolid particles upon the critical rotative velocity when particles suspendin liquid in the PLR.It is discovered that the rotative velocity willreduce with the installation height of propeller lowered untill it islowered to a height called the critical installation height,which equalsabout 0.58 di. Based on the behavior of particle suspension from the literatures andapplying the isotropy theory of turbulece,this papper establishes a ma-thematical model and derives a mathematical expression of the minimumrotative Reynolds number when particles are maintained to suspend inliquid in the PLR.

本文研究了固体颗粒在PLR中的临界悬浮条件,由涡流作用机理和实验结果得一个出了关于临界转速的关联式。

It is a designing better seclected model of local to make design for improvement. The ship lines advantage they have V head, U-shaped and haft tunnel steen. To a fishing boat of low draught can hold a longer diameter of propeller. But also to raise their speed of ship. Besides, seakeeping performance is a better performance even in rough seas is 4-5.

本设计选取当地较优母型为据,进行改型设计。型线特点是前倾首V型,尾U型带半隧道式,对吃水浅的渔艇能容较大的直径的螺旋桨,有利于航速的提高。此外,耐波性好,抗风能力4至5级。

When the power required by propeller is so high that the shaft speed cann't arrive a rated value,the tip of propeller can be cut to decrease its load.This paper presents the method for determining the cut amount of diameter of propeller, which is based on a series chart of characteristics of cut propeller.The series chart suited with conventional propellers of high speed ship is also provided in this paper.The calculated results by use of this method are in good agreement with ones of ship...
