Expertise in multi-scale aeraulics for system design
Flow disturbance: influence of singularities in industrial plants
Most of the conveying systems in industrial plants have various singularities that cause significant changes in the flow. Their influence can lead to flow changes such as phase separation, instabilities and changes in the flow regime.
In this context, it becomes complex to apprehend the head losses in very particular networks.
EOLIOS is specialized in multi-scale aeraulic studies. This expertise allows us to bring you a thorough analysis of the actions of a gas or a liquid in your networks in order to provide indications for the design of your various systems.
Pressure loss study
In fluid mechanics, , the pressure drop of a liquid or a gas due to the different friction against the walls of a tube or a sheath is called ” pressure drop “. This friction generates a dissipation of the mechanical energy of the fluid. There are two types of pressure drops :
- Linear or regular losses : Energy loss due to friction on the walls of a conduit or a pipe whose roughness may vary.
- Singular losses : Energy loss due to the various singularities of the network such as section changes, elbows, inlets or outlets…
The origin of pressure drops
Loss of regular loads
The regular pressure losses are caused by friction on the walls of the network. The more viscous the fluid, the greater the friction. The viscosity of the fluid combined with the micro asperities of the network increases the friction of the fluid and consequently the dissipation of energy.
For a given liquid or gas, the pressure drops depend on two things:
- Pipe roughness: The materials used for the ducts or pipes have more or less roughness on their surface. This property of the material results in a regular pressure drop of varying magnitude.
- The type of flow There are different types of flows, such as laminar, transient or turbulent flows. The difference between these flows is reflected in the ratio of inertial forces to viscous forces.
Singular pressure loss
Regular pressure drops occur when a change in geometry takes place within the network. These geometry changes cause flow disturbances and can sometimes lead to vortex phenomena within the pipe itself.
Typically, regular head losses are changes in cross-section cross-sectional changes, elbowsor systems attached to the network, such as expansion boxes, dampers, heat exchangers, heat exchangers, etc.
Their influences can lead to flow modifications such as phase separation, instabilities and changes in the flow regime. Singular pressure losses are in most cases the source of the major part of the pressure losses.
Installation optimization and design aids
In the industrial fluids sector, the pressure drop is a well known phenomenon that must be taken into account. EOLIOS accompanies you in your steps of calculation of loss of charge in order to answer your needs as well as possible. We are able to provide a precise calculation of the pressure drops of your systems and to guide you towards the optimization of your networks and your installation.
3D modeling & CFD simulation of your networks
The realization of a numerical twin as well as a CFD simulation of your networks is possible within the framework of a calculation of pressure loss. CFD simulation, whether stationary or transient, can be a valuable aid in capturing all the phenomena at play in your systems.
