Projekthistorie

Advanced Transient FEA: Supersonic Aerodynamic Particle Dispersion

R&D Engineering Group (Czech Republic)
Developed and executed high velocity multi body particle dynamics simulations in LS DYNA to evaluate discrete mass transport profiles across symmetric omnidirectional (4 pi steradians, approx. 1000 particles) and highly directional (60 degree half angle cone, approx. 1800 particles) flow configurations.

Implemented an interpolated, velocity dependent drag coefficient matrix (Cd(M)) to simulate severe supersonic deceleration from an initial velocity of 2280 m/s, replacing standard constant drag models to precisely capture velocity decay vectors across discrete target planes up to 50 m.

Benchmarked numerical spatial concentrations (approx. 5.97 particles per m^2 at 10 m) and trajectory decay vectors against classical fluid particle reference solutions, achieving near perfect correlation with an exceptionally tight maximum error margin of +5.08%.

Automated the extraction and spatial reconstruction of particle level state timelines using Python and LS PrePost from binary solver databases (D3PLOT, NODOUT, GLSTAT); verified numerical solver stability via energy balance checks to maintain an elite energy drift well under 0.1%.

Commercial Sports Equipment Manufacturer (USA Client)
Imported parametric complex geometries from SolidWorks into LS DYNA to execute high fidelity, transient non-linear explicit dynamic simulations replicating structural impact against rigid surface boundaries.

Established precise physical governing equations by defining an initial velocity vector of 6.2 m/s (1.98 m drop
height) and deploying advanced CONTACT_AUTOMATIC_SURFACE_TO_SURFACE card parameters to capture localized surface mechanics.

Calibrated complex elastoplastic polymer material models within the solver to achieve high-accuracy correlation, successfully validating a first rebound height of 0.802 m (80 cm) to prove official regulation compliance.

Extracted and evaluated transient displacement-time histories and strain plots to analyze multi-axial structural deformation, kinetic energy dissipation rates, and elastic recovery profiles under maximum compression.

Turbine Chamber CFD Analysis and Optimisation

USA based renewable energy project
Determining the hydraulic head derived the design for the turbine chamber, calculation of flow rate from the inlets, and further operating conditions.

StarCCM+ was used to carry out the simulation for the CAD model and further fluid domain generation carrying out the polyhedral mesh with prism layers to analyse the boundary layer.

SST k-omega turbulence model ensured smooth transient state simulation through which flow separation,
recirculation, pressure loss and velocity profiles were extracted.

Introduction of the Turbine using DFBI and further optimisation of the setup for better RPM & efficiency.

Steam Injection Tank Thermal & CFD Analysis

Energy Project (Canada Client)
Applied Eulerian Eulerian multiphase flow models with Rayleigh Plesset cavitation/phase change kinetics in ANSYS and STARCCM+ to resolve transient 130 PSIG steam condensation.

Utilized SST k-omega turbulence closures with prism layer mesh refinement (y+~1) near the injector nozzles to capture high velocity kinetic dissipation under a 4ft hydrostatic head.

Executed transient Conjugate Heat Transfer (CHT) to demonstrate a successful bulk fluid temperature ramp from 80 F to 170 F within the strict operational timeframe.

Validated buoyancy driven macro mixing velocity vectors, proving complete elimination of localized hot spots
and ensuring a uniform 48-hour adiabatic thermal hold across all 26,000 gallons.

Pole Crash Test Simulation (Automotive Safety)

Client Work
This engagement involves simulating a pole crash test in LS Dyna to evaluate structural behaviour under both frontal and side impacts, with particular focus on the pole vehicle interaction. The objective was to benchmark performance against Euro NCAP style requirements and provide reinforcement strategies to improve safety compliance.

Detailed CAD models of the vehicle structure and pole barrier were developed in SolidWorks and prepared for explicit crash simulation, with calibrated material definitions, contact models, and boundary conditions replicating regulatory standards.

Results had shown intrusion depths of 210-220 mm, peak occupant loading of 28 g, and total energy absorption above 65 kJ. Acceleration-time histories confirmed controlled load transfer throughout the event, while quantified load paths revealed critical stress channels in the side sill and floorpan. Deformation occurred within 61 ms, highlighting localized failures and guiding targeted reinforcement concepts.

Deliverables shared to date include validated solver decks, preliminary crash animations, deformation contour plots, and interim analysis reports, with final documentation and recommendations scheduled for completion at project close.

Pump Impeller Design & Hydraulic Optimization

Government backed energy project
Commissioned within a government backed energy program, this project delivered a centrifugal pump impeller for large scale pumping operations. The mandate was to increase efficiency and reliability while ensuring the design remained practical for industrial manufacturing and long term operation.

The impeller was developed in SolidWorks with multiple design iterations refining blade geometry and hub configuration. Performance was validated through CFD simulations in Ansys Fluent and StarCCM+, with a focus on reducing hydraulic losses, improving velocity balance, and extending cavitation resistance under demanding duty cycles.

The optimized design achieved a 14% efficiency improvement, a 20% reduction in hydraulic losses, and a 30% improvement in flow uniformity, while extending cavitation margin by 12% compared to baseline. These results directly supported project targets for lower energy consumption and stable long term operation.

Propeller Design & Mixing Optimization

Government Backed Energy Project
Within a government backed energy program, a 14 inch Michigan Wheel DJ 355 propeller was redesigned to transform industrial scale mixing operations. The challenge was clear: eliminate stagnant zones that undermined process reliability and reduce escalating energy costs in continuous use tanks.

Using SolidWorks for CAD and StarCCM+ with MRF for simulation, the propeller underwent multiple design refinements. The final configuration achieved a 100% elimination of dead zones, a 12–15% reduction in energy input per cycle, and a 312 Pa lower pressure drop versus baseline.

This result established a new benchmark for energy efficient industrial mixing demonstrating how precision design and CFD driven optimization can directly deliver cost savings and operational resilience. The engagement concluded with deployment ready CAD assemblies, CFD validation reports, and a full optimization dossier for scale up.
