R&D

Our company ascribes great importance to research and development during the entire manufacturing process. Our goal is to produce better quality, less energy-consuming systems and to offer these products to our customers. Our Company closely follows all the latest developments in fan technology and energy efficiency fields, for the benefit of our customers and attempts to develop its products in this direction.

All these activities are carried out by our R&D department. In addition, studies are also conducted to provide new products that the shareholders of the sector is seeking for.. Alfer, thanks to these capabilities which it has developed, has established an infrastructure that is capable of making both the aerodynamic and mechanical designs and analysis of the fans as well as the testing of the fans with its own sources by 100%.

Thanks to our advanced CFD (Computational Fluid Dynamics) capabilities, we can perform the simulations of the fan working conditions in order to see in a computer environment how the fan will act in all the operation points.

How Alfer Designs the Fans?

sayfa-18-alfer-fani-nasil-tasarliyor

Using the final design inputs, Alfer performs the conceptual design of the fans with CFD simulation software program, which is an interactive conceptual design program enriched with the addition of Alfer’s unique designs correlations. The design to be made is loaded in CFD software and then, the flow analysis and the modeling of the flow inside the fan is carried out. Thus, we are able to view on our monitors what trajectory a dust particle follows and whether there is any dust accumulations on the blades, through CFD software.

When the correct conceptual design has been reached, mechanical design based simulation procedures gets started along with specifi software programs. At this stage; model analyses, shaft analyses, and the analyses of the mechanical forces acting on the rotor are carried out. This way, it is possible to see any physical deformations, whether the steel material used in the production can meet the strength values and whether there are any regions in the fan exposed to extreme stress physically, and the required improvements are made if necessary.

Alfer, after having completed mechanical analysis studies as well, decides whether the fan is manufacturable or not.

How Alfer Chooses the Fans?

Fan Selection and Performance Curves

Fans consume too much energy during their operational life, which is generally dozens of times of their initial investment
cost. This means that, for an operation plant, the best fan is not the one with the lowest initial investment cost but it is
the efficient fan that consumes less energy while providing the desired performance. Therefore, the selection, design,
manufacturing and operation of the fans should be based on lifetime cost principles.

Fans should be designed and used, as much as possible, according to the operation points as needed by the system.
Thus, fan design and selection should be made in accordance with the determined flow rate and pressure and with other
operating conditions.

Alfer Engineering makes the selection of the most efficient fan and prepares the fan curves appropriate for this selection,
performing the necessary calculations through the software program used when making fan selection.

HOW DO WE INCREASE THE FILTER PERFORMANCE?

untitled

Alfer Engineering ascribes great importance to research and development during the entire manufacturing process. Our goal is to produce better quality, less energy consumption and to provide these products for our customers. Alfer Engineering closely follows all the latest developments in filtration technology and energy efficiency fields, for the benefit of our customers and attempts to develop its products in this direction.

Flawless filtration units are designed by means of CFD analysis,

– Thanks to our advanced CFD (Computational Fluid Dynamics) capabilities, we can perform the simulationsof the filter unit related working conditions in order to see the flows in a computerized environment.

– Thanks to our advanced CFD working conditions we can have a chance to simulate all operation points and detect the behaviors of the filter at these points.

– Thanks to CFD analysis we can examine the behaviors of flows at the points which are impossible to be reached by traditional measurement methods without corrupting the flow characteristics.

With the CDF simulation, we can provide following concepts,

*Fluid behaviors dependent on stable regime or time

*Pressure, velocity and temperature distributions

*Heat transfer

*Single-phase and multi-phase flows

*Constant density fluids and compressible fluids

*Particles and smoke distribution

*By means of cleaning system analysis and consumption of compressed air performance diagramsi tailor-made nozzle and venturi equipments
