BOUNDARY LAYER THEORY INTRODUCTION The concept of boundary layer was 1st introduced by L.Prandtl in 1904. Figure 7-1. Viscous flow around airfoil A structure having a shape that provides lift‚ propulsion‚ stability‚ or directional control in a flying object. Boundary layer is formed whenever there is a relative motion between the boundary and the fluid. Boundary layer thickness: 1. Standard thickness - signified by ‚” it is define as the distance from the boundary layer

Introduction The unconsolidated undrained (UU) Triaxial Test is a quick method of estimating the shear strength of a soil. The soil which undergoes the test is sheared to failure without prior consolidation meaning this test is perfect for soil samples which are undisturbed however this is never the case. This means that results have to be interpreted with care so the undrained shear strength of the soil is not underestimated. For the purpose of this test I used the results posted by Dr.Brian Mc

Executive summary In this day and age we have so many forms of transport to take us far or near‚ but the safest and fun way to travel is by flying. Even though it is the safest way of transport accidents still happen due to many reasons. The factor this report will be dwelling on is the way weather phenomena affect these accidents. The purpose of this report is to highlight the possible dangers of certain weather phenomena and research ideas to help prevent these accidents from occurring again.

This will involve a detailed report and further questions. The simplest strategy is to do the lab.] Notes For the First Year Lecture Course: An Introduction to Fluid Mechanics School of Civil Engineering‚ University of Leeds.

affect an aircraft‚ in this report I will specifically talk about the microburst. Microbursts are powerful downdrafts associated with thunderstorms. We have been able to identify microbursts through many studies regarding wind shear and meteorology research. Wind shear is basically a rapid change in wind velocity and direction that happen because of many factors in weather conditions. Such conditions include frontal activity‚ temperature inversions‚ and thunderstorms amongst other factors.

numerically investigated. To the best of author’s knowledge‚ the effects of slip boundary condition in the presence of dynamic effects of nano particles have not been investigated yet. The results of the present paper show the flow velocity and the surface shear stress on the stretching sheet and also reduced Nusselt number and reduced Sherwood number are strongly influenced by the slip parameter. The objective of the present study is to analyze the development of the slip effects on the boundary layer
