A comprehencive range of Mains power connectors from Bulgin We can offer a main power connection for your equipment ,hunderds of such connectors are produced by Bulgin

The natural draft cooling tower is the right choice for large power plants.It offers the following advantages :power saving (no power consumption to induce air flow- no fan).environmentally friendly.no mechanical noise (no fan).safety of operation.no recirculation as the plume is rejected at high level.limited plot area.limited maintenance.high longevity (generally more than plant life expectancy).Payback period between 8 and 16 years depending on several factors.Hamon offers both basin or water collecting devices. This last solution, developed by Hamon, is recommended for large cooling towers.It offers the following advantages :less pressure drop in the air inlet.reduction of pumping power.decrease of acoustic pressure in air inlet

Acoustics Rich and powerful acoustic features for your simulation needs Actran Acoustics is the foundation module of the Actran family and is both a standalone tool and a pre-requisite for advanced modules like Actran VibroAcoustics, Actran AeroAcoustics or Actran TM. Actran Acoustics contains a wide set of acoustic modeling features making it the CAE tool of choice for simulating a large variety of problems, from the simplest component to the most elaborate system. The Actran Acoustics product relies on Free Field Technologies’ exclusive powerful, robust, fast and reliable acoustic finite and infinite element library. Sound fields in cavities are easily analyzed with Actran Acoustics which offers both modal and physical approaches. Absorbing walls may be modelled in detail using impedance conditions or porous material models. Actran Acoustics is also uniquely suited for sound radiation analysis where it brings unprecedented efficiency, speed and productivity to your analysis process. Actran Acoustics features seamless interfaces with most FEA structural analysis codes like NASTRAN, ABAQUS™ or ANSYS™. Actran Acoustics also offers powerful features for analyzing sound propagation in ducts and may be used for designing e.g. intake and exhaust lines or air distribution systems in buildings, aircrafts and cars. Among the many advanced features available in Actran Acoustics are the handling of a mean flow field (convected acoustic propagation) and temperature gradient effects. Specific elements are also available to handle visco-thermal effects important when sound waves propagates in narrow ducts or thin cavities (eg: hearing aids, solar array panels, etc.). Pressure field generated by the vibration of a powertrain. Target Applications: Sound radiation by vibrating structures: powertrain, engine components (oilpan, intake manifold and air filter, valve cover, etc.), compressors, electrical motors, loudspeakers and more. Intake and exhaust noise, including complex mufflers and silencers. Air conditioning units and distribution systems (calculation of transfer matrices coefficients). Sound absorption inside passenger compartment of cars, trains and aircrafts. Sound propagation in complex media with mean flow or temperature gradient. Audio devices such as telephones, hearing aids or musical instruments.
