Measurement & Control

Engineers focusing on measurement and control systems — including valves, flow meters, sensors, filters and pumps — face special challenges: They are tasked to ensure a perfect level of accuracy while working with complex systems and multiple physical effects.

Software from ANSYS can help these engineers to simulate the performance of many measurement and control systems — at an incredible level of detail. Deep computational fluid dynamics (CFD) capabilities from ANSYS support these professionals as they model and assess structures and flows, working to create innovative measurement and control systems with applications in a wide range of industries.

Physical and thermal stresses, aperture sizes, flow volumes, multidirectional flow patterns and fluctuating pressures can all be modeled using ANSYS tools in a dynamic simulation environment that replicates real-world operating conditions. Software from ANSYS can be used to model the acoustical effects of various measurement and control devices.

Powerful engineering simulation tools from ANSYS can help engineers to develop and improve many kinds of measurement and control devices.

Valves Valves

Measurement and control valves are subject to a variety of changing pressures, stresses and strains that must be carefully considered in initial design along with ongoing design enhancements. Fatigue and failure must be predicted with great accuracy to ensure continuous valve operation. Software from ANSYS enables engineers to model and study valve aperture designs and sizes, multidirectional flow patterns, turbulence, deflection and deformation, fluid– structure interactions, crack growth rates, and other factors that affect performance. The tools are capable of modeling many valve types:

  • Compressor valves
  • Sliding gate valves
  • Pressure relief valves
  • Globe valves
  • Complex coupled magnetic/hydrodynamic valves requiring the application of multiple physics

Filters Filters

CFD capabilities from ANSYS support engineers in modeling and enhancing flows through a variety of filtration and separation systems — whether they are used to clean dust from the air, remove liquid contaminants, or perform other functions in a range of industrial applications. The tools allows measurement and control engineers to model flow fields, pressure fields, flow distributions, heat/mass transfer rates and other factors that contribute to reliable filter performance. Engineers can assess filter surface pressures, exchange rates, permeability levels and the effect of turbulence when developing new filtration/separation system designs. 

ANSYS technology has the features and  functions to model a broad range of gas and material filtration systems:

  • Spin filters
  • Bag filters
  • Vokes filters
  • Gravitational separators
  • Membranes
  • Hydrocyclones

Pumps Pumps

In pumping applications, flows are both steady and unsteady, creating special challenges for measurement and control engineers. Software from ANSYS helps to model and improve dynamic performance characteristics as vortices, cavitation, pressure degradation, vapor formation, flow acceleration and turbulence effects. ANSYS has the capabilities to simulate the performance of both single- and multi-phase pumping flows as well as a variety of pump designs — including centrifugal pumps, sucker rod pumps and other devices.
