Control, limitation and mitigation of noise,
shocks, vibrations and seismic movements on constructions, equipment, pipe
networks
|
Buildings, equipment and pipe networks are generally affected by shocks & vibrations generated by the operation of equipment or fluid flow through pipe networks. Additionally, on sites with average or high earthquake, seismic movements need to be considered in the design of equipment, pipe networks and buildings.
Such shocks and vibrations affect the proper operation of the technological equipment & components, damage the buildings’ structure where they are installed in and generate waves and noises that propagate to the environment, affecting the foundations of sensitive equipment and components, and also generate a discomfort for the operation personnel and for the occupants of buildings.
Depending on the generating source, shocks and vibrations may exhibit widely different dynamic characteristics such that specialized solutions, based on careful analysis of individual dynamic characteristics, may be required to achieve a complete elimination or a significant reduction of their effects.
This section presents some applications of the SERB solution to enhance the safety level of structures equipment and pipe networks against shocks, vibrations and seismic movements. |  device for

Renewable Energy – sun, wind, wave
At present and in the
near future, over 70% of the electric power production is obtained from fossil
fuel burn-up, a process which is generating gaseous and solid pollutants. The
process of uranium nuclear fission used for the electric power production
generate some amounts of long half-life radioactive wastes, which, in case of
accidents, are likely to negatively affect large areas in the long run.
The limited quantity
of classical and nuclear fuels and the direct and indirect pollution which
accompany the electric power production based on such fuels, demand, among
other things, the search for new sources of primary energy and efficient procedures to
transform it into electricity.
Wind Energy
Unfortunately, the
process to convert the air stream (wind) kinetic energy into mechanical
rotation energy used in the past and even
nowadays, has not experienced essential improvements. Such
a technology is allowing the use of around 20% of the wind kinetic energy.
The need to increase
the unit power of wind-power turbines has recently led to enlarging the blade
sizes up to 75m length, with negative consequences both on the economical feasible operation
of the wind potential in a certain area and on the environment.
Despite such a
progress, wind power, which is actually for free and all over the world,
is now inefficiently used and represents a very small
share in the electricity power production (less than 2%).

Wave
Energy
The continuous motion
of wind transfers energy from the air mass in rectilinear motion to a water
mass causing an oscillatory motion known as wave. Waves behave as energy
accumulators as once formed they propagate over large distances due to water’s
incompressibility and non-dissipative quality.
Waves are a form of
energy storage transferred by the wind to oceans and seas.
According to current
estimates, wave energy can be exploited on a viable economical basis when its
linear potential surpasses 15~20 kW/m (that is the
usual measurement unit for the linear potenatial of waves, the annual average wave power, on a
meter width of the wave's crest,
parallel to the shoreline).
The largest storage
of wave energy is concentrated on the west coasts at latitudes between 40° and
60° in both the northern and southern hemispheres. Energy contained in wave
crests varies between 30 and 70 kW/m, reaching levels of about 70 kW/m in the
West Atlantic ocean of Ireland and in the extreme south of Latin America, and
100 kW/m in New Zealand.

Vehicles aerodynamic resistance
During
operation classic automobiles with internal combustion engines, generate a
large amount of gases pollutants. The reduction of pollutants cannot be
achieved up to the desired values with all the improvements brought to the
combustion systems.
The
highest consumption of fuel per vehicle is due to air resistance, which depends
on the square of their movement speed. The new solution to reduce air
resistance is based on the combined use of passive and active type devices
mounted on the back which manage to change the distribution of the air flow to
decrease of the negative pressure in the rear.
