Axial fluid velocity
around a hydrodynamically shaped body.
The Marschall Acoustics Group has a wide variety of finite element solvers for external and internal flow. These can be coupled to a variety of structural and boundary layer models, including those for turbulent flow. Marschall Acoustics Instruments Pty. Ltd. may not have the capability of large government laboratories and some giant aerospace companies, but we don't have their overheads and high prices either! Modest sized commercial problems are our specialty. Customers have included government agencies, petroleum exploration and production companies, mineral extraction and processing firms, marine vessel manufacturers, food processing firms, and various motor sports organizations.
Marine structure subject to fluid flow loading.
Marschall Acoustics Instruments Pty. Ltd. is well experienced and equipped
to handle stress analysis of marine and other structures subject to a variety
of static and dynamic loads. Standard steel structures are easy,
but we can also handle structures made of multiple materials and even of
many composite materials. Various stresses and displacements can
be solved for and clearly displayed. Dynamic solutions for moving
or vibrating structures include the usual quantities as well as statistics
on components of stress and displacement. Mode shapes and frequencies
are also available. Structures can be coupled to moving fluids, subject
to acoustic and other radiations, and exposed to static and time varying
thermal loads. Sensor and structural components with a piezo-electric
response can have their output predicted in response to both external signals
and structural vibrational noises.
Fluid velocity around flexible pressure mine sweeping bodies.
The Marschall Acoustics Group
has performed many theoretical and numerical studies of flexible bodies
in axial fluid flow. Our engineers have also participated in numerous
experimental programs to measure and control vibration of such bodies and
the fluid flow over same. These flexible bodies have included constant
and non-constant diameter towed hydrophone arrays, solid seismic streamers, influence mine sweeping
devices, composite aircraft components, and various communications antenna
Marschall Acoustics Instruments Pty. Ltd. staff are also experienced in ship quieting. Our staff have analyzed and designed many shipboard noise and vibration reduction systems. These include engine and compressor mounting systems for seismic exploration vessels, offshore research ships, generator isolation for research vessels, and various components of submarines.
