The paper “ Determining the Behavior of Two Different Fluids Flowing through Pipes of Different Lengths” is an opposite version of a lab report on physics. Fluid dynamics is one of the important fields of engineering. It is both important in our lives and also in the running of machines. Fluid, therefore, plays a significant role in ensuring that the machine moves efficiently. Fluid composed of air, water, oil, and other liquids that we need daily. The study of fluids will help us understand the behavior of different fluids and what makes them different from other fluids.
Air and water which form fluids make our body mass and the movement of air in the atmosphere ensures we have sufficient oxygen that we require to sustain our lives. At the same time, 75% of our body is water and the movement of these fluids across our body system is important in improving our health. Fluids are therefore necessary for supporting carbon-based life forms. To study the biological systems, it is only important to apply the knowledge of fluid dynamics. Fluids are important in the transportation system and they greatly affect recreation and can also be used in entertainment.
It is impossible for speaker sound to reach our ears without the movement of air and we cannot even breathe when there is no air. Based on the above findings engineers must have the knowledge of fluid behavior in order to examine different systems they come across. The purpose of this study is to investigate the behavior of different fluids with different densities, pressure, and temperature. To determine the correct result, it is important to follow the correct procedure required when setting up a simulation.
The correct set up will be able to investigate the flow of two different fluids that have density and viscosity variations. It will also determine the flow of fluids with two different pressure conditions, fluids with two different Reynolds numbers, and those with two different Mach numbers. CFD codes usedIn the examination of the flow rate of two different fluids through the pipes, it is important for the researcher to define the expected flow rate within the pipe and also to describe the behavior of these fluids under given conditions (Tomboulides et al, 2015).
In all cases, it is vital to know the density of the fluid, its viscosity, and temperature changes for the study to continue. It is also necessary to determine the length of the pipe, inlet and outlet diameter, and the diameter of the main pipe. All these factors must be known in order to understand the behavior of two different fluids under the study. In this study, only two multiphase simulation capabilities are applied to assess the flow rate and the general behavior of two different fluids in different conditions.
STAR-CCM+  code is used in this case to create a platform for an advanced multiphase flow model to examine the behavior of two different fluids under analysis (Amicis, 2014). Another important code used in this study was Nek5000 which was mainly used to develop a platform for examining thermal fluids in order to determine the behavior of some fluids when there is an increase in temperature.
