Introduction
Eco-friendly natural refrigerants as alternative refrigerants

Due to toxicity of NH3, flammability of hydrocarbons, and high pressure and low COP of CO2, blends are more effective.

CO2 and HC mixtures have superior heat transfer properties with reduced cycle pressure and flammabilit ....etc

Innovative Designs for Magneto-Rheological Dampers



Introduction
The main purpose of this chapter is to introduce the topic of magneto-rheological
(MR) dampers to the reader. Also presented is an explanation of the mechanism
through which MR fluid works. Lastly, the project objectives and the approach
taken to evaluate different MR damper designs are discussed.

1.1 An Overview of Magneto-Rheological Dampers
In recent years, manufacturers have shown an increased inte ....etc

Important two-phase fluid mechanics problems that are dominated or significantly affected by capillary effects are not oddities but rather daily events in our lives. Seemingly unrelated topics such as the economics of satellite television and pulmonary health and safety research share capillary fluids physics. Current and future miniaturized two-phase heat transfer loops and fuel cells possess similar concerns. This seminar presents research in a number of capillary fluids topics on Earth and in orbit. An energy method code, Surface Evolver, is ....etc

Abstract
Purpose: This paper presents the properties of magneto-rheological fluids and their recent applications and development In recent years. This paper particularly deals about the use of MR fluids in shock absorbing system in cars.
Reviews: The theoretical research results of the properties and applications obtained in the past decades and their developments are also reviewed.
Findings: It is very clearly and well understood from the presented paper that replacement of the traditional methods w ....etc

Electrorheological fluids are suspensions of extremely fine non-conducting particles (up to 50 micrometres diameter) in an electrically insulating fluid. The apparent viscosity of these fluids changes reversibly by an order of up to 100,000 in response to an electric field. For example, a typical ER fluid can go from the consistency of a liquid to that of a gel, and back, with response times on the order of milliseconds. The effect is sometimes called the Winslow effect

The ER effect

The change in apparent viscosity is dependent on the ap ....etc

Fluids in Motion


Velocity and Flow Visualization

Primary dependent variable is fluid velocity vector V = V ( r ); where r is the position vector.

If V is known then pressure and forces can be determined.

Consideration of the velocity field alone is referred to as flow field kinematics in distinction from flow field dynamics (force considerations).

Fluid mechanics and especially flow kinematics is a geometric subject and if one has a good understanding of the flow geome ....etc
