    DRILLING FLUIDS The key to making the rotary drilling system work is the ability to circulate a fluid continuously down through the drill pipe‚ out through the bit nozzles and back to the surface. The drilling fluid can be air‚ foam (a combination of air and liquid or a liquid. Liquid drilling fluids are commonly called drilling mud. All drilling fluids‚ especially drilling mud‚ can have a wide range of chemical and physical properties. These properties are specifically designed for

The solver is using a full-scale time-marching 3D viscous model. Underlying equations‚ three dimensional Navier-Stokes equations in their conservation form‚ are being solved by using a Finite Volume method‚ where equations are integrated over the finite control volumes. Thereby‚ the solution domain is subdivided

    Introduction The thin aerofoil theory is very useful as it relates values of lift to small angles of attack for aerofoils with low camber and thickness without taking into account the viscosity of the flow. The thin aerofoil theory assumes that the flow is 2 dimensional‚ inviscid and incompressible. It can be used to predict pressures and forces on very thin cambered surfaces with the thickness approaching zero‚ along with finding the lift

    1. INTRODUCTION A diesel engine is an internal combustion engine that uses the heat of compression to initiate ignition to burn the fuel‚ which is injected into the combustion chamber during the final stage of compression. Diesel engines have wide range of utilization for automobiles‚ locomotives & marines and co-generation systems. However‚ large problem is still related to undesirable emission. The six-stroke engine is a type of internal combustion engine based on the four-stroke

    CHAPTER 5 STATES OF MATTER INTERMOLECULAR FORCES Intermolecular forces are the forces of attraction and repulsion between interacting particles (atoms and molecules). Attractive intermolecular forces are known as van der Waals forces. van der Waals forces include dispersion forces or London forces‚ dipole-dipole forces‚ and dipole-induced dipole forces. A particularly strong type of dipole-dipole interaction is hydrogen bonding. Dispersion Forces or London Forces Observed between non-polar molecules

    Characteristics of a Good Hydraulic Fluid Viscosity  Viscosity is a measure of a hydraulic fluid’s resistance to flow. It is a hydraulic fluid’s most important characteristic and has a significant impact on the operation of the system.  When a hydraulic oil is too thin (low viscosity)‚ it does not seal sufficiently. This leads to leakage and wear of parts. When a hydraulic oil is too thick (high viscosity)‚ the fluid will be more difficult to pump through the system and may reduce operating
