Fluid Mechanics with Historical Perspective is partof a series of modules covering the broader subject of thermodynamics at theUniversity of Bath. At the start of each hour-long lecture, the tutor gives a15-minute input on the aspect of discoveries and developments related toflight. This historical...
Transient flow is a fluid dynamics condition where the velocity and pressure of a fluid flow change over time due to changes in system status. These changes may be caused by the starting or stopping of a pump, opening or closing of valves, or fluctuations in supply pressure from reservoirs ...
In most modern heat pumps, electrical energy powers a compressor, which drives a compression鈥揺xpansion cycle of refrigerant fluid between two heat exchangers: a cold evaporator and a warm condenser. The efficiency, or coefficient of performance (COP), of a heat pump is defined as the thermal...
Most cars that have an engine-driven cooling fan have a thermostatically controlled viscous clutch— the temperature of the fluid actually drives the clutch. This clutch is positioned at the hub of the fan, in the airflow coming through the radiator. The fluid in the clutch gets thicker as ...
A stand of drill pipe usually sits vertically in back of the drill rig. This portion of the pipe is typically one of a collection of parts that form the, which moves the drilling fluid with the help of pumps. A drill string usually consists of a, the drill bit, and the drill pipe....
then the flow is steady; otherwise, it is unsteady." That is, steady flows do not change over time. An example of steady flow would be water flowing through a pipe at a constant rate. On the other hand, a flood or water pouring from an old-fashioned hand pump are examples of unstead...

Pump flow rate is plotted on the x-axis of a pump flow curve, also called a system curve, and pump head is plotted on the y-axis. Pump head is a term used to describe the pressure loss in a pump. It is a combination of the elevation or static head, which is the difference in ...

Simcenter System Analyst 2021.1 is reinforced with the capability to execute optimization loops within a multi-criteria analysis workflow. A typical application of such capability is to perform a fuel consumption/performance optimization before evaluating drivability criteria and obtain the best result of ...
