Hydraulic Modeling of Complex Fluids
Message Message Hydraulic Modeling of Complex Fluids Hydraulic Modeling of Complex Fluids Published February 2024 Download (coming soon) Keywords Hydraulic Modeling AFT Fathom AFT Impulse Non-Newtonian Slurries Bingham Plastic Share Summary Modeling of complex fluids like non-Newtonian fluids or settling slurries should not be intimidating. The basic steps are very similar to that of conventional hydraulic models for single-phase, Newtonian fluids like water. However, a few additional set-up steps are required as you build your model. Fathom and Impulse both have the capabilities of modeling non-Newtonian fluids built-in to the traditional software package. But to model settling slurries, the Settling Slurry add-on module is required. Once again, both Fathom and Impulse have the option to add this module. This file will go over the basic information and steps required to model these types of fluids. This file will not delve deep into the theory behind the fluid dynamic principles, but rather focus on the process of building [...]
Emulsified Oils vs. Grease Traps: What You Need to Know
Are you considering installing a grease trap or oil interceptor at your facility to fix high FOG in your wastewater? There is more to this process than meets the eye. We often have new customers come to us after installing large, underground grease traps and interceptors with little to no reduction in FOG. Before taking action, we encourage you to learn from our experience with emulsified oils in grease traps, which can help you make a more informed decision with your wastewater treatment and save money for your business.
Ontario Premier Ford meets with JNE Consulting team at Algoma EAF milestone event
The Algoma Electric Arc Furnace (EAF) project reached a major milestone in late February with the erection of the first sections of structural columns for the new melt shop building. JNE Consulting was invited to a photo commemoration ofthe event that included Ontario Premier Ford, Minister Pirie, Mayor Shoemaker, and Mr. Ross Romano, MPP for Sault Ste Marie.
JNE reaches annual Movember fundraising target
With this year’s fundraising total, JNE has raised over $25,000 towards men's health awareness since the team’s formation in 2018. We are extremely grateful to everyone who supported our efforts this year and helped us contribute towards a global mission of reducing men's mortality rate by 25 per cent by 2030. We are proud to support the Movember Foundation and look forward to future fundraising efforts.
JNE at the OSPE Engineering Conference 2022
Representatives of the JNE Group of Companies attended the Ontario Society of Professional Engineers (OSPE) Engineering Conference in Ottawa, Ontario on November 3, 2022. The event, Canada's largest forum for engineering, diversity, and recruitment, was a fantastic opportunity to connect with young professionals, students, and subject matter experts in the engineering industry.

Safety Considerations for Pneumatic Pressure Testing
Message Message Safety Considerations for Pneumatic Pressure Testing Safety Considerations for Pneumatic Pressure Testing Published October 2023 Download (coming soon) Keywords Pneumatic Pressure Test Stored Energy Minimum Safe Distance Scaled Consequence Factor ASME PCC-2 Repair of Pressure Equipment and Piping Share Summary Pneumatic pressure testing poses a significant health and safety risk due to the stored energy of the test gas, especially on larger volume piping. This can affect the operations of clients or construction activities and should be considered when specifying pneumatic pressure tests. Safe distances for personnel are proscribed in ASME PCC-2 Repair of Pressure Equipment and Piping. Minimum safe distance is 30m (100ft) and increases with stored energy and risk of fragments being thrown. The safe distance can be reduced utilizing mitigation techniques included in ASME PCC-2. When specifying a pneumatic pressure test always consider stored energy and look to eliminate the need for the testing or substitute hydrostatic. Reducing the safe distance below 30m (100ft) should always be a last resort. Codes and Standards ASME PCC-2 Repair of Pressure Equipment and Piping Part 5 Examination and Testing – Article 501 Pressure and Tightness Testing of Piping and Equipment Mandatory Appendix 501-I Pressure/Leak Testing Mandatory Appendix 501-II Stored Energy Calculations for Pneumatic Pressure Test Mandatory Appendix 501-III Safe Distance for Pneumatic Pressure Test Mandatory Appendix 501-IV Risk Evaluation Considerations for Pneumatic Pressure Test Solution/Best Practice Part 5 of ASME PCC-2 and the related mandatory appendices are clear on the requirements for pressure testing piping and pressure equipment: Hydrostatic tests are preferred and should only be excluded from pressure testing if: The equipment, piping, and/or supports, including foundations, cannot adequately support the liquid weight. The equipment or piping cannot be dried, and traces of the test liquid may result in contamination of the system or its contents after returning to service. The equipment or piping has internal linings that could be damaged by the test medium. If a pneumatic pressure test is selected due to hydrostatic exclusion, then the following shall be adhered to: A stored energy calculation per Appendix 501-II shall be completed. The maximum stored energy should not be greater than 271,000,000J (200,000,000 ft-lb) When calculating stored energy, the total volume of a pressure vessel shall be considered. For piping systems, a length of 8 pipe diameters may be considered for any single failure analyzed. If the stored energy is greater than 271,000,000J the system shall either be broken into smaller test sections, a minimum safe distance per Appendix 502-III calculated and adhered to and/or protective barriers installed. A hazard analysis should be performed to evaluate the risks associated with stored energy. The minimum safe distance for a pneumatic pressure test regardless of stored energy is 30m [...]
