1. The boundary layer is investigated for the situation that fluid is passing through an object, where around the object the layer of boundary is formed. Imagine the circumstance that the aircraft is flying in the sky, the wing is cutting through the air. The boundary layer around the wing could be observed, which is a thin and a highly sheared region. It is the layer that looks random and chaotic but also has structure on it. The Boundary layer is a complex structure, which is classified from Laminar

Task 2 – P2 A Newtonian fluid is a fluid that exhibits constant viscosity regardless of any external stress applied to it, like mixing or a sudden application of force. Like water; this flows in the same direction regardless of whether it’s left alone or agitated. A Newtonian fluid, by definition, can only be affected by pressure and temperature together, or temperature, but not pressure on its own. Water The viscosity of water can be affected by temperature, and by pressure and temperature, but

result in a lower velocity. Velocity is the speed and direction of a given object or substance, and viscosity is the thickness of a fluid. Fluids that have lower viscosities are thinner, and therefore able to move with greater speed. On the other hand, fluids that have a high viscosity, such as pahoehoe lava, are thicker and move slowly. Because the viscosity of a fluid can impact its speed, temperature ultimately also affects the lava’s velocity. While experimenting, the hot maple syrup was able to

microchannel instead of hand based MEMS (microelectromechanical) [3]. Third, the components are highly integrated in a small chip including pumps, valves, channels, reactors, etc. [3]. The fourth point is the precision drive technology mainly using fluid power,

this paper, we introduce two new functions on the semi-infinite interval namely Rational Gegenbauer and Exponential Gegenbauer functions and we apply them as basis functions in Tau method to solve the boundary layer flow of a magneto-micropolar fluid on a continuous moving plate with suction and injection. These functions are a general case of rational Chebyshev and Legendre functions and this is the first time that they are used in Tau method. The operational matrices of derivative and product

1. Conductive arteries – Conductive arteries are the most proximal compartment of the coronary arterial system. Their diameter is generally ranging from 500 μm up to 2-5 mm. These are large epicardial coronary arteries that work as a capacitance function for the blood flow. They have very low resistance to blood flow and therefore, the pressure drop along the length of conductive arteries is negligible. The conductive arteries have an inbuilt characteristic of maintaining the shear stress by changing

the CSF characteristics of the HVS in order to embed the watermarking data on selected wavelet coefficients of the input image. The selected coefficients dwell on the detail sub bands and the information about the edges of the image were contained in them. Hence, the embedded information becomes invisible by exploiting the HVS which was less sensitive to alterations on high frequencies. The success of their method in terms of robustness and transparency was illustrated by results
