Features

FUNDAMENTAL
is essential to follow your developments on the flowbench, in fact, have a flowbench and don't process the results obtained in a timely manner threatens to ruin your work.
Often the software related to the flow bench does not make fully developed and refined the data collected, which limits the interpretation of results and information that can be drawn to proceed with the development of the component in a better way. The needs shown by several of our customers have encouraged us to create a series of software dedicated to the analysis and interpretation of the statements from the flow bench.

The classic simple comparison of volumetric flow rates (cfm, m3/s, etc.) measured from the flowbench, regardless of how it has performed the test, the test conditions, areas of the elements, etc.. can often lead to erroneous considerations sometimes frustrating months of work with related work thrown to the wind.

With software FLOW ANALYSIS can be rather clear results, being able to understand clearly whether the direction taken is the right to development, as margins improved to the benefit of time and costs.

Each element has specific features flushed NT-Project has therefore decided to create separating software for the main elements that are flushed to the flowbench.

COMPLETE
only from the test results is able to derive a set of information that allow you a comprehensive and effective analysis of flow test performed.
Together with the test results should be included the geometric data of the item that you are flushing so the software calculate the coefficient of discharge to show the actual efficiency of the component and this is crucial to make realistic comparisons between different flow tests.

In addition to this aspect the software FLOW ANALYSIS allow to calculate the discharge coefficient taking into account how the test is really made, indeed the characteristics of the flowbench and the test mode can affect the results, so it would be appropriate to the classical definition of a more refined calculation of the coefficient of discharge.

Finally, the FLOW ANALYSIS software calculates the thermo-fluid dynamic conditions in the minimum section of element fluxed, it is essential to understand the characteristics of the flow and if the flow test can be a real indication of what will be in operation or if you need to change the test conditions.

SPECIFIC
for each element flows were introduced special features that add information to flow test for a better development of the component.
The software have then special features targeted to the specific characteristics of the element fluxed.

In the analysis of flow test about head of four stroke engine FOUR STROKE FLOW ANALYSIS has been included the ability to see under what conditions is the intake stroke as a function of the engine characteristics (stroke, bore), of the head (number and geometry of valves), of the valve train (open and close the valve, maximum lift) and of the rpm of interest. With this feature, the software determine the difference in pressure that the engine actually creates to the different lift at the rpm considered, then you can adjust the flow bench in the real conditions and to establish a flow as similar as possible to what will happen later in the engine operation .

In the analysis of flow test about cylinder of two stroke engine TWO STROKE FLOW ANALYSIS has been included in calculating the timing area of ports fluxed, it allows to have a clear picture of the instantaneous area in the engine cycle, and then you can make more comprehensive assessments on engine timing.

In the analysis of floe test about reed valve REED VALVE FLOW ANALYSIS was included simulation of the opening of the reed petals under varying conditions of pressure and the characteristics of the petals themselves. In this way, in addition to calculate the effective area of flow in the different test conditions, you can see the movement of the petal to the benefit of the choices to be made for this key element to optimize the operation of the engine.

TWO STROKE FLOW ANALYSIS

For the reed valve is important to know the mechanical properties of the petals, in particular density and modulus of elasticity. Often these values are not declared by the supplier, for this NT-Project has proposed a scheme of instrument that combined with a dedicated software allows to calculate realistically the modulus of elasticity, and then verify the goodness of the petals purchased or otherwise assist in the selection of a petal than the other depending on the conditions. In this short presentation you will see the software features and craftsmanship instrument needed..

Requirements of Flowbench

it is sufficient that the floebench displays the flow measured and the pressure difference of the test. The software allows you to enter data in all the units of measurement, so data can be entered directly without having to do conversions or calculations.
