The mutual desire for higher fuel economy and greater performance along with stringent emission regulations set by the government for diesel engines necessitates enhanced air-fuel mixing for proper combustion. The design of intake port plays a major role in an engine design, development and optimization, as it controls the power developed, fuel consumed and exhaust emissions from the engine.
Swirl angle calculation . Swirl angle is an important parameter to determine the quality of the flow ingested by the pumps. Hydraulic Institute  prescribes the method that needs to be employed for estimating this parameter. Experimentally the swirl is measured using a swirl meter shown in figure 1. The swirl

Spiral Curves Made Simple COURSE OBJECTIVE This course is intended to introduce you to Spiral Curve calculations along centerline alignments. It is assumed that you already now how to calculate simple curves and generate coordinates from one point to another using a bearing and distance. Offsets to Spiral Curves and intersections of lines with Spiral Curves will not be discussed in
• The Swirl Angle is the angle between the measured representative exhaust gas temperature, at varying loads, and the known combustor source-location. • However, the swirl angle is not a rigidly controlled parameter and could be expected to vary between units - it should be treated only as a tool.

CONCLUSION Above figures show the predicted flow pattern in the CFD for simulations of the 10"X600 master meter in line with the 10" test meter or the 10 ...
Roof Pitch Calculator Results Explained. Slope - The slope of a roof is represented as X/12, where X is the number of inches in rise for every 12 inches of run.This is very useful information for many purposes, especially for roof framing - the slope, sometimes called pitch, is calibrated on speed squares.. Angle - The angle of a roof is the same as the roof's slope, except instead of being ...
Apr 30, 2012· [Note: It might be the case that this information has already been shared on the CFX forum but this is an effort to bring it under one thread.] Quantifying swirl becomes very important in some situations where you would like to reduce it or even sometimes when requirement of design is to increase the swirl.
(Today, they're probably all produced using software simulations--but only for newer machines.) Problems like cracked combustion liners or failing side deals do not always exhibit the same swirl angle. The point is: Swirl angle charts are not the be-all, end-all method of troubleshooting all exhaust temperature spreads.
Calculating swirl and tumble for either a plane or volume of your model can be done using the calculator operations within EnSight. In this particular example, I will use an In-Cylinder Model to illustrate this process, however this is not unique to In-Cylinder type applications, and thus can …
The angle of a slope can be calculated using the online Slope calculator. Examples of the angle of a slope include such things as the angle of the driveway, the pitch of a roof, the angle of a hill and so on. GoodCalculators.com A collection of really good online calculators for …
PDF CALCULATIONS FOR SWIRL COMBUSTORS M. S. Anand* and A. T. Hsu Allison Engine Company P. O. Box 420, Speed Code T-14 Indianapolis, EN 46206 S. B. Pope* Sibley School of Mechanical and Aerospace Engineering Cornell University, Ithaca, NY 14853 Calculations are reported for recirculating swirling reacting flows using the joint velocity-scalar
The experimental facility, shown in Fig. 1A, includes a swirl burner with a movable 12-vane swirl cascade. The cascade is adjusted to impart the desired degree of swirl intensity to the combustion air stream that passes through a 0.10 m o.d. passage and flows along the fuel passage. The swirl intensity is a measure of the angular momentum of the
Sundial Angle Calculator. This sundial angle calculator helps you to find the gnomon angle. Sundial is a device used to know the time of a day with the apparent position of the sun in the sky. It has a flat dial and a gnomon, which casts the shadow over the dial. As per the sun's position, the gnomon aligns with different sundial hour lines.

The velocity profile should be referred to as the axial velocity profile. As the velocity vector can be resolved into three mutually orthogonal components, the velocity profile only represents the axial component of velocity. fig.(2) showing the Swirl Angle which explains the definition of flow swirl and swirl angle.
If your solar panels will have a fixed tilt angle, and you want to get the most energy over the whole year, then this section is for you. A fixed angle is convenient, but note that there are some disadvantages. As mentioned above, you'll get less power than if you adjusted the angle.
