Presentazione HEAD DESIGN by NT-Project

Head Design is a software designed to help technicians and tuners in the fluid dynamic development of the engine head. Currently the optimal processing of intake and exhaust ducts is determined exclusively by numerous attempts at the flowbench or by complicated CFD simulations, instead with this software you can have with simplicity effective indications on a fluid-dynamic basis to optimize the engine head.

How it works?

In practice usually the tuners have directly the head to be worked and not have available the three-dimensional drawings of intake and exhaust ducts to study them through CFD simulations, for this the software Head Design was designed to recreate the main geometry main of the duct through simple workshop measurements , which can be made directly on the head, or creating the mold of the duct and measuring it.

Thanks to simple measures it is possible to insert easily in the software the geometric characteristics of the section main of the duct, of the valve guide and of the valve.

For what concerns the geometry of the main section of the head ducts in the software there is a millimeter area with two spline curves that allow to define the shape of the internal and external profiles of the duct simply dragging control points and seeing in real time how to edit the curve. The coordinates of the points of control can also be entered manually, then measuring, the mold of the duct, or some key dimensions of the duct in the engine head, you can easily recreate the geometry to study and optimize with the software.

After entering the required data, you can see the geometry that has been recreated for the duct, the guide valve and valve.

This geometry is aimed at identifying the main geometries characteristics of the duct in terms of lengths, curvatures and impediments, in order to make a calculation on the fluid-dynamic basis of the main factors that determine the losses during the flow passage through the duct.

After displaying the inserted geometry, you can proceed to the calculation. The software performs a flowbench simulation of the duct and determines, through appropriate fluid dynamics calculations, the losses that will occur through the duct at the passage of the flow.

At the end of the calculation the software shows as a function of the lift valve the following quantities:

TOTAL DISCHARGE COEFFICIENT
FLUID DYNAMIC DISCHARGE COEFFICIENT
FLOW RATE
GEOMETRIC AREA
EFFECTIVE AREA
AVERAGE GEOMETRIC AREA
AVERAGE EFFECTIVE AREA

Thanks to the calculated quantities you can have a clear picture of the characteristics of the duct, both in terms of passage areas, both for what concerns pressure and flowrate losses that will occur for the flow.

These results will be the reference to study through the software the geometric changes that allow you to optimize the duct to reduce fluid dynamics losses and increase the flowrate at all advantage of the engine performance.

In fact, after the calculation on the initial geometry will be possible to simulate the geometric changes that you intend to make on the duct and verify if they will be improving or less. This will allow you to find the correct direction first to proceed with the realization , thus avoiding many practical attempts before to reach the desired solution.

This phase in the software is very simple, in fact in a specific zone is shown a millimeter area, with drawn the initial geometry in black, which can be easily changed simply by moving the points of control and seeing in red the new geometry.
After entering the changes to be made on the duct will be sufficient perform the calculation to see if the interventions hypothesized actually bring improvements.

Based on the results it will be easy to understand the direction of the interventions to be carried out, and then working with the software will be possible to identify the changes that allow to optimize the geometry.

The software Head Design is therefore a tool for all those who they can not use CFD simulation, but that want to equally have a help from the calculation to optimize at the best the engine head.
In fact, although the software works on a simplified geometry characterizing the duct, it is able to seize the main effects of the changes that you want to make and then orientate the development in the best direction.
