What is Pressure and Buoyancy Force – Fluid mechanics

What is Pressure and Buoyancy Force – Fluid mechanics

The forces known as buoyancy, drag, and lift arise when fluids interact with a solid structure or vehicle. Drag and lift forces arise when there is relative motion between a fluid and a solid object. A vehicle can either move through the fluid (as an aircraft moves through air,for instance) or the fluid can flow […]

Importance of Fluids in the Design of Micro and Macro systems

Importance of Fluids in the Design of Micro and Macro systems

Fluid mechanics plays a critical role in the design of a wide range of mechanical systems across many orders of magnitude. Large laboratory equipment is now being replaced by microfluidic devices that combine pipes, valves, and pumps to deliver and process fluid samples on a single silicon chip. These devices, sometimes referred to as a […]

Dimensionless Numbers used in Fluid Mechanics

Dimensionless Numbers used in Fluid Mechanics

Mechanical engineers often work with dimensionless numbers. These are either pure numbers that have no units or groupings of variables in which the units exactly cancel one another—again leaving a pure number. A dimensionless number can be the ratio of two other numbers, and, in that instance, the dimensions of the numerator and denominator will cancel. One dimensionless number […]

Laminar and Turbulent Fluid Flows & Reynolds Number

Laminar and Turbulent Fluid Flows & Reynolds Number

While traveling in air plane we hear pilot instructing to fasten the seat belts because of the turbulence at the time of severe weather conditions or airflow over high mountains. There may be some other firsthand experience about the flow patterns. Fluid flow patterns are generally divided in to laminar and turbulent fluid flows. Now , […]

Properties of Fluids & Their Applications

Properties of Fluids & Their Applications

Although you already have some intuition as to the behavior and properties of fluids in everyday situations, we begin this article with a seemingly simple question: From an engineering standpoint, what exactly is a fluid? Scientists categorize compositions of matter in different ways. A chemist classifies materials according to their atomic and chemical structures in the context of the periodic […]

Laser Beam Machining (LBM) Principles and Applications

Laser Beam Machining (LBM) Principles and Applications

As the name implies in Laser beam Machining the source of energy is the LASER (Light Amplification by Simulated Emission of Radiation) . The laser beam focuses optical energy on the surface of the workpiece. A laser beam can be so powerful when used with lens system that it can melt and vaporize diamond as […]
