Supersonic flows occur in process devices such as a jet pumps. simulation of ice formation on a heat exchanger).
The simulations may also take into account phase transitions and related thermal effects (e.g. Multiphase simulations allow to model different states of matter, e.g., liquid-gas (e.g.
Using such functions of the CFD software, it is possible to simulate very complex processes occurring in process devices and find the appropriate design solution. combustion) that can affect the density of the fluid, take or produce the energy. The flow simulation may also include chemical reactions (e.g. simultaneous presence of steam and water) and phase transitions. It is also possible to take into account the multi-phase flow (e.g. Additional functions give opportunity to calculate concentration of species carried by fluid and to find e.g. CFD Flow Simulationsįlow simulations are used to predict the fluid movement (gases or liquids that meet the condition of a continuous medium) and estimate the pressure and velocity. The termal simulations may include heat exchange resulting from the flow of fluids in contact with the analyzed structure (coupled model). Correct estimation of the temperature during steady and unsteady operational conditions is necessary to properly carry out structural analyzes. Thermal loads may have major influence on their performance. The process equipment usually operates under thermal stresses. The figure below shows results of the pressure test pool dynamic calculations in the event of pressure device breakup. The simulation results may support the safety analysis of the pressure equipment. In the process sector dynamic calculations may be necessary to determine the impact of sudden increase in pressure inside a tank or a sudden sealing breakup.
#Pv elite crack crack
We perform crack propagation calculations on the basis of Paris's law and the integral J. In welded structures the initiation of fatigue crack usually occurs at the weld edges of the elements due to stress concentration.
For the remaining devices the fatigue strength is determined e.g. In case of pressure equipment, where the operating pressure and temperature may vary in time we check the fatigue strength primarily for critical welded joints based on the guidelines of EN 13445-3 or ASME VIII standards. We perform FEM static analyzes of non-pressure tanks such as silos, storage tanks, etc., using appropriate procedures and guidelines according to Eurocode 1, 3, 8 for weight, wind, snow and seismic loads.įatigue calculations are required when variable cyclic loads occur. not typical solutions or load combinations we use the DBA (Design by Analysis) method with the finite element method (FEM).įEM simulations provide in-depth understanding of the complex relationships between individual design parameters, improving the efficiency and durability of equipment, reducing costs and reducing design time. For cases where the DBF method is not applicable, e.g.
#Pv elite crack software
We use Visual Vessel Design and PV Elite software for the DBF (Design by Formulas) calculations to check compliance with the relevant standards. We have many years of experience in structural analyzes of pressure equipment in accordance with the PED 2014/68 / EU directive, PN-EN 13445, AD-2000 and ASME VIII. We provide design and analysis services for the process and energy sectors.
