###### Effect of using insert on the flow pressure in cylindrical silo

1 Introduction The use of cylindrical silo with discharge hopper is widespread in many industries, in which materials are stored and processed until they are used in industry. Finding the dynamic flow pressure produced on the wall and the hopper of a silo during filling and discharging is one of the most important stages when designing silo and operating it safely. [ 3 ] In addition to that, the type of flow patterns produced in the silo has a significant effect on the distribution of flow pressure exerted on the silo wall and hopper. It has been agreed that

###### Steady flow of a power law fluid through a tapered non-symmetric stenotic tube

1 Introduction Blood flow through stenotic arteries is a subject of recent investigation from the past few decades. Development of stenosis in the arteries is one of the leading causes of circulatory disorder. In medical terms, "narrowing of anybody passage" is called stenosis. This growth is abnormal and unnatural in the thickness of arterial wall that produces at different positions in the cardiovascular system under particular conditions. It has been observed that stenosis is due to the close association of the conditions of flow in the blood vessels

###### Optimization of Power System Development Using Acceleration Factor for Power Flow Calculation

## Optimization of Power System Development Using Acceleration Factor for Power Flow Calculation

The dynamic optimization process is analyzed from the viewpoint of simplifying the power flow calculations. The aim of the work was to reduce the calculation time using all admissible algorithms. Although the conventional iteration methods are simple and fast enough, the use of the so-called relaxation principle leads to increased calculation time. The paper exemplifies the power flow calculation based on the iteration method using acceleration factor. Proposals concerning the modelling of a power system are put forward in the aspect of its future development.
