What is ADEM?

ADEM is a compact software for acoustic design of all types of mufflers, silencers, resonators and flow duct networks in a user friendly Windows environment.  It can also be used for the post-processing of microphone signals acquired in source and system measurements in fluid machinery intake and exhaust systems .

Features of ADEM include:

Multi-layered graphical user interface for constructing block diagram models of flow duct networks; multiple sources and outlets can be included; system block diagram can be linked to a drawing or a sketch.

Open end radiation into fractional free-fields and diffuse fields.

Signal analyzer for driving sources, audio play, and post-processing of results or measured signals.

User-friendly input datasheets with formula writing, syntax and compatibility checking capabilities.

Parametric and doe calculations with selected parameters and arbitrary constraints; direct, stochastic, and inverse optimization capabilities.

Results of calculations are plotted on-line and can be stored in a file.

Element database contains passive two-ports and multi-ports in 1-D and 3-D; one-port and two-port sources; multi-ports have variable number of ports; measured and FEM based two-port elements can be imported; users can create (without any programming) new elements in 1-D and 3-D and new one-port sources.

Processing of microphone signals acquired in measurement of one-port source characteristics and two-port transfer matrices by state-of-the-art methods.

Frequency analysis and order analysis capabilities under ambient gradients and fluid options (gas, liquid, burnt product, refrigerant, etc.); mean pressure losses in elements are calculated along with acoustic calculations.

Extensive on-line help, tutorials and compact installation.  

Applications include:

Cars, trucks, motorcycles, locomotives, industrial and agricultural vehicles, airplanes, helicopters, ships, and boats, etc.; generator sets and plants, gas turbines, chimneys, cooling towers, compressors and blowers; venting of a high-pressure gas in power generation plants, natural gas compressor stations; pipeline blowdowns, process control relief valves, blowdown tanks, autoclaves, bypass valves, steam ejectors hogging vents; heating, ventilation and air conditioning (HVAC), guns, and so on.
