Computational fluid dynamics

Thermal properties of BHE The thermal properties of the ground are mainly determine by the minerals , water saturation and porosity. The thermal conductivity is depend upon porosity when the porosity increase thermal conductivity is gradually decrease due to that water and air are less conductive as compare to minerals, and on the other hand heat capacity increase with higher water content. During the installation of heat exchanger soil loss it structure due to drilling then the thermal…

Objective: In this laboratory experiment three objectives were sought after. These objectives were to first, create a separation scheme. Second, perform basic biochemical qualitative analytical tests. Lastly, identify the major components of milk. Introduction: The three goals in this experiment were desirable due to the fact that it gave knowledge on what is actually digested when milk is consumed. This is notably important to the children and adults that are lactose intolerant. 1 Many…

The viscoelastic behavior of bucky paper reinforced epoxy laminar composite materials for structural application has been evaluated through Dynamic Mechanical Analysis. The effects of heating rate, sinusoidal forces on glass transition temperature Tgwere studied. In DMA LVDT controlled sinusoidal force is applied and measures the response of the input as shown in the figure 3. It measures parameters which are the signature properties of the material under supervision like storage modulus, loss…

Differences in thermoregulation patterns observed in the Monarch Butterfly, Danaus plexippus Many Lepidoptera species thermo-regulate using several patterns, physical and behavioral. These patterns are usually observed as movements from the shade and cooler areas to a place exposed to the sun as well as utilizing mechanical flight to generate heat. However, some species have intermediate behavioral patterns, often a mixture of basking and heat production, also known as endothermy (Kingsolver…

The active region displayed in Figure 1 show a larger pore and several smaller pores in G-band. Bright points and several micropores are also visible. This active region was observed from 18:08 UT to 23:38 UT. However, there are three gapes from 18:42 to 19:08 20:21 to 20:47 and 21:59 to 22:26. Figure 1 shows the first image of the time series. Figure 2 illustrates the evolution of the fine structures at the inner part of the granules (i.e. towards umbra) at the pore boundary. Several dark…

determined using the wind tunnel experiment. Also understand the aerofoil characteristic in terms of fundamental fluid dynamics. The coefficient of pressure (C_p) is calculated by the ratio of static pressure (P-P_∞) over the dynamic pressure of the free stream (1/2 ρU_∞^2) using the equation: C_p=(P-P_∞)/(1/2 ρU_∞^2 ) . The lift coefficient (C_L) is determined by lift force over the freestream dynamic pressure times the wing area (S) C_L=L/(1/2 ρU_∞^2 S). Aerofoil is one of the most…

The purpose of experiment six was to better understand how to measure and read volumetric flow rate of water through a pump, and to better understand how flow meters work. In this experiment, the relationship of the plot between the orifice and Venturi meter pressure differential showed many correlation with each other. The volumetric flow rate had a square root relationship with the previous stated pressure differentials. The error in this lab was also extremely low appearing at around…

Fluid dynamics relating to bluff bodies, non-streamlined structures or streamlined bodies at large angles of attack, remains a critical focus of study within the fluid mechanics community. One particular area of interests involves the occurrence of fluid-induced vibrations, or more commonly known as vortex-induced vibrations (VIV’s), exerted on bluff bodies. Due to the production of vortex shedding beyond bluff cross sections, an alternating pressure distribution produces periodic fluctuations…

relationship between flow and ∆P through a Venturi in a pipe at a various distances from the Venturi. THEORY: The Venturi flow meter is an equipment that uses the Bernoulli Effect and a manometer pressure gauge to measure the rate of flow of a liquid or fluid that is flowing through a pipe. There is also a part in the venture equipment that has a reduced cross-sectional area. When the liquid goes through this part, the speed (velocity) tend to…

heat will be introduced to the device and the output of light remains constant, ensuring that all pictures are exposed to the same degree of lighting which is a requirement for effective image analysis. Once all of the settings have been in place fluid will be passed through the device and pictures of the system will be taken at periodic intervals over the course of several days. As has been described, air will be passed through the channel to allow greater visibility when images are taken. When…
