Download file to see previous pages OBCs have been under investigation for some time now given the advantages they provide compared to conventional mixing and reaction vessels. The greatest amount of research concerning flow characterization inside OBCs has been performed in laboratory conditions only. Though carrying out laboratory experiments is required for scientific validation but this process could be simplified through the use of computer-aided means. Advances in numerical modelling and solution techniques over the years have meant that computer-aided simulations can be used just as reliably as laboratory experiments in order to investigate the physical phenomenon. However, in order to utilise computer-aided means, it is necessary to find fitting solution models for the situation provided since there is no one size fits all solution methodology through numerical solutions. The current research has undertaken the discovery of fitting models that are required to simulate and find solutions for flow inside OBCs. In order to carry out this research, the researcher has utilised ANSYS 13.0 in collaboration with CFD software.
All simulations carried out in order to further this research were based on single-phase flows only. In addition, three different scenarios were investigated where the diameter, the frequency and the amplitude were varied respectively. The results from these computer simulations were compared to previous laboratory research from published and validated researches. The contention was to apply various different computing models in order to decipher which models were best suited to the OBC flow phenomenon. In addition, the primary area of the investigation remained flow turbulence emulation since turbulence plays a vital part in mixing inside OBCs. Three different turbulence models were used namely LES, DES and k epsilon. 
The study was conducted to investigate the response of flow in OBCs as various parameters were modified. ...Download file to see next pages Read More

Numerical Precision Numerical precision Floating point numbers Floating point numbers arethe most common way of representing real numbers in computers in recent times. The numbers are mostly represented in a scientific notation which includes a base number and an exponent. For instance, 123.46 can also be expressed as 1.23456 x 102. Floating point numbers range from 1,000,000,000,000 to 0.0000000000000001. In the expression of floating point numbers, they are expressed in a normalized manner in which the radix point is put after the non-zero digit Storage in memory Floating point numbers are...

Floating-point arithmetic is reflected as an obscure issue by alot of persons because it is universal in a computer scheme. Every language almost has a floating-point data type, meaning computers that consist from PCs to supercomputers of floating-point accelerators, compilers would oftenly be needed to compile floating-point procedures and then almost every operating system should answer to floating-point exclusions like excess. This paper discusses the aspects of floating-point computer scientist should know to avoid some petty mistakes than can rather...

Numerical Investigation of Single Phase Flow Oscillatory Baffled Columns... analysis The solution of differential equations often can not be limited to simple trivial methods. A number of equations can be solved analytically including systems of equations and equations of higher degree. But nevertheless there exist a big number of real problems where differential equations which describe the state of real-time processes can not be solved using simple differentiation and integration rules. These types of problems (especially systems of differential equations) are solved numerically using a number of similar algorithms which are based on the principles of numerical...

Numerical Control Computer Numerical Control (CNC) popularly known as Numerical Control (NC) is the automatic control that is integrated into mechanical tools and equipments used in manufacturing mass products. These automated instructions are abstractly encoded into a program that is used as a language by the tools. These machines were introduced in the 1940s and their gross use was initiated in the 1950s although these did not use the modern computation language that is afforded by computer programs. However, in the modern times, the machines have been well developed so that little man power is ...

Single-phase motors find us in vast applications ranging from home to small farms and industries. However, the successful running and little maintenance of a single phase motor will depend on the type and design of the motor selected for a particular application. Since most of the motor failure and other problems arise from the mismatch of the motor type with required application, a few types of single...

Prof’s High Frequency Oscillatory Ventilation (HFOV) The lungs are just one part of the respiratory system and the site of gas flow and exchange. The primary goal of the respiratory system is to deliver oxygen to the blood and to remove carbon dioxide from the blood to the environment. Sometimes, for a variety of causes, the lungs will fail. At this point, the person will have two options: die, or be temporarily transformed into a cyborg. Those who choose the latter are placed on a mechanical ventilator, which allows control over the pressure, volume, and rate of air delivered to the alveoli. The...

Numerical integral

...Numerical Investigation of Single Phase Flow Oscillatory Baffled Columns... Mathematics 13 November Numerical Integral The history of integrals s back to the 17th century. The basis of integrals was formed in about 1635 by an Italian mathematician known as Cavalieri. His work was the fundamental modern step towards the branch of calculus. However, the development of integrals has had many contributions by different mathematicians. Before the development of integral calculus by Gottfried Wilheim Von Leibnz and Sir Isaac Newton, several other mathematicians had made several developments using the ideas of Archimedes of Syracuse (Elroy 63). Cavalieri was one of the pioneer proponents of the idea that quantities too small cannot be divided into...

The Single Phase Transformer

...Numerical Investigation of Single Phase Flow Oscillatory Baffled Columns... Numerical Investigation of Single Phase Flow Oscillatory Baffled Columns... Transformer is a device that transfers electrical energy from one circuit to another which are kept electrically isolated. It does it through inductive or more specifically magnetic coupling. As shown in figure 1, change in voltage in primary winding creates changing magnetic flux that cuts the secondary winding and produces a proportionate secondary voltage. Its major application is to change the current or voltage level before transmitting electrical energy over long distance. Figure 1 shows the transformer schematic symbol and the corresponding commonly used Steinmetz model is shown in Figure ...
