V8 Engine Block Sand Casting: Design Exploration of Runners, Risers and Chills through Flow and Solidification Simulations
April 18, 2024 | 1:00pm ET
A v8 engine block is a complex casting with several thick and thin-walled features. A large volume of metal alloy needs to be poured well to fill the entire casting and compensate for shrinkage of metal, eliminating defects and porosity in critical and stress tested areas of an engine block’s life cycle. The webinar aims to show an exploratory design process starting with the engine block thermal solidification analysis and various factors involved in designing a casting feeding and riser system.
We will cover relevant material such as:
- Selecting casting orientation to fill
- Choosing the best sprue-runner configuration to pour metal minimizing turbulence, entrained air and surface oxide defects
- Riser placement and volume considering predicted shrinkage porosity and thermal modulus
- Chill volumes and placement to alleviate hot spots and thermal management within sand mold and casting
- Sprue cup and pouring criteria to represent realistic ladle or crucible metal transfer
- Venting requirements and compressibility in sand molds for large and complex thick-thin-walled castings
How to achieve optimal welding processes with FLOW-3D WELD
May 9, 2024 | 1:30pm ET
Laser welding can substantially improve the quality, productivity, and profitability of manufacturing processes by offering a higher level of precision and control. Laser welding process defects such as overheating, entrained porosity and lack of fusion can be mitigated by optimizing processing parameters to specific alloys. CFD simulations of melt pool dynamics and solidification provide key information on how process parameters affect porosity, heat affected zones, and microstructure evolution.
Understanding the behavior of the molten weld pool helps solve industry challenges such as welding dissimilar metals, where over- or under-mixing in the inter-metallic layer can cause porosity or crack propagation. Another challenge is found in keyhole welding, which is necessary for welding thick sections, but which often leads to keyhole instabilities that are difficult to control. CFD simulations are useful to explore industry solutions such as beam shaping and wobbling, to improve keyhole stability and increase throughput. In this webinar, CFD Engineer Garrett Clyma will break down how FLOW-3D WELD can be employed to develop process windows and explore novel technology to address industry challenges in laser welding processes.
Rock Scour Assessments for the Water Industry: A Methodology Using 2D/3D Fluid-Solid Numerical Coupling
Presented by the Australian Water School
May 29, 2024 | 8:00pm ET
Join our panel of expert presenters as they explore rock scour assessments in the water industry, including:
- The risks associated with rock scour at water infrastructure;
- Methods for estimating rock scour;
- A numerical modelling approach including iterative fluid-solid coupling with 2D/3D CFD models;
