Advancing Electroplating Applications through Numerical Simulation: A Focus on Zinc-Nickel Electrolyte Systems
- Date: Monday 13th May
- Location: Reef F
- Time: 2:45pm PDT – 3:30pm PDT
- Track: Simcenter
- Speaker: Bashir Alnajar, CFD engineer Corrdesa
This presentation presented a numerical workflow using Zinc-Nickel (Zn-Ni) electroplating to replace cadmium in aircraft landing gear manufacturing.
It highlights the complexity of numerical modeling due to Hydrogen gas evolution, involving turbulence and multiphase fluid dynamics, making it a ‘Multiphysics’ problem involving fluid dynamics and electromagnetism. The study analyzes the effects of electrode geometry and operating conditions on plating thickness, current density, and Zinc-to-Nickel ratio, demonstrating how precise control can optimize plating thickness. The methodology, validated by experimental data, offers a scalable and robust approach that is beneficial for sustainable and efficient manufacturing.
Simplifying CFD for Corrosion Risk and Severity Prediction in Diverse Applications through a Specialized Toolset
- Date: Tuesday 14th May
- Location: Reef E
- Time: 4:30pm PDT – 5:15pm PDT
- Track: Simcenter
- Speaker: Julio Mendez, Lead Senior CFD engineer Corrdesa
Here, we will show the development of an innovative Corrosion Toolset designed to simplify Computational Fluid Dynamics (CFD) for predicting and managing corrosion in industries such as automotive and aerospace. It supports using Digital Twins and facilitates multiphysics simulations where CFD engineers, material scientists, and stress analysts can collaboratively work on the same model, maintaining a “Single Source of Truth” for all revisions. This integration fosters collaboration from the design’s inception, simplifying complex CFD processes for Materials and Processes (M&P) professionals, thus enhancing proactive corrosion management across various industry sectors.

About Bashir Alnajar
Dr. Bashir Alnajar received his Ph.D. in Mechanical and Aerospace Engineering from the University of Colorado Colorado Springs (UCCS) for his work on numerical modeling of lipid-coated ultrasound contrast agent microbubbles using the Couple Level Set Volume of Fluid Method (CLSVOF) and Transient Network Theory.
Upon receiving his PhD, he became a postdoctoral researcher at Lahjavida. His postdoctoral research focused on enhancing the radiofrequency (RF) heating capabilities of Magnetic Nanoparticles (MNPs) for cancer therapies and simulating heat transfer from MNPs to surrounding tissue when exposed to a magnetic field.
Currently, He is working at Corrdesa, where he uses Multiphysics Computational Fluid Dynamics to implement electrochemical modeling into corrosion risk assessment and optimize surface finishing processes as plating and anodizing.
