Design/Analysis Services

cfdfigure1Becht Engineering has extensive experience and expertise in the design and analysis of mechanical components, including those for very severe environments such as very high temperatures and pressures. The coupling of extensive design experience and analysis capability enables us to take on the most challenging design projects. Added to this mix is our extensive experience in the relevant codes and standards, as we have participated in and chaired many of the committees that are responsible for those that govern the design of this equipment.

Becht Engineering thrives on design challenges. We have designed first of a kind equipment for next generation applications and pressure equipment for pressures in excess of 6000 bar and temperatures in excess of 1000oC (1800oF). We are experts in the relevant codes and standards, with more than 40 positions held in ASME, API and ASTM Codes and Standards Committees, and having chaired many of them.


Becht Engineering analytical capabilities include finite element analysis, pipe stress analysis, computational fluid dynamics (CFD), heat transfer, mechanical dynamics and vibration, fluid transients, structural analysis, fracture mechanics and pressure vessel design/analysis. We have a broad range of commercial software tools we use in our work, and when required to properly do the job, we develop our own tools. A Becht advantage is our expert abilities in interpretation of the results, which comes from our design experience and codes and standards expertise.

Computational Fluid Dynamics (CFD)

cfdfigure1 thumb

Becht has the Computational Fluid Dynamics (CFD) program, STAR-CCM+ as part of our suite of software packages. STAR-CCM+ is capable of handling 3D or 2D, time dependent, multi-phase flow problems with a variety of turbulent models to choose from. It also can integrate with our FEA package, Abaqus, for a coupled approach of solving fluid-structure mechanics interaction problems.

One application for STAR-CCM+ is modeling flow through valves to calculate the pressure drops. It can dynamically move open and close the valve during the analysis to calculate pressure drops at different conditions. It can record data at multiple points or create a movie of the flow.

Figure 1 (click) shows a screenshot of one of the frames from a movie output of a valve. Such a movie output of streamlines over time provides us a strong view of any potential problem areas in the valve or any object that is being analyzed.

Another application that Becht has used STAR-CCM+ in is for guillotine pipe ruptures. These are best handled with a 2D model because of the uniform dispersion of contents from a fully ruptured pipe. The 2D model allows for refinement of the mesh and also allows for the use of smaller time steps which can more accurately track the pressure wave propagation through the cavity in which the steam is dispersing. Data is recorded to address a number of potential concerns a blast wave presents. The first of which is the pressure time history directly in-front of the rupture location as shown in Figure 2. Another important parameter to check is the reflection multiplier of any corners or walls, as shown in Figure 3. Finally the overall movement of the blast wave can be tracked as shown in Figure 4


Elevated Temperature Design

Becht Engineering has substantial experience and expertise in elevated temperature design. Dr Becht is a member and the former Chairman of the ASME Boiler and Pressure Vessel Code Subgroup on Elevated Temperature Design and has developed elevated temperature design methods that have been incorporated into codes and corporate standards. Included in his work are ASME funded R&D projects to develop new elevated temperature design rules for Section VIII, Divisions 1 and 2.

Becht Engineering has performed many design, analysis and troubleshooting projects for elevated temperature equipment, that is, equipment operating in the creep range for the material of construction. This includes design of equipment at such high temperatures and conditions that the design criteria needed to be developed, as was done for the Marble Hill Nuclear Reactor Annealing project involving 1000oC (1800oF) ducting that was only required to operate for a relatively short duration. These criteria were accepted by authorities such as DOE, NRC and National Labs without comment.

Our expert knowledge has enabled us to develop practical solutions to many elevated temperature problems.

Failure Analysis

In some occasions, damage is not detected prior to failure.  In these cases, plant operations involve us to assist them in determining the root cause of the failure.  We apply the same approach used in Fitness-For-Service.  In failure analysis, we form up teams including the relevant discipline specialists, including mechanical, materials and equiprment specific experts such as rotating and fired equipment experts.  Our findings and recommendations are used to prevent failures in other equipment.
