This work presents a CFD–DEM simulation of a rotary seed dryer. Hot air flows through the inclined drum at 350 K while the drum rotates at 20 RPM. Seeds are modeled with the Discrete Phase Model (DPM) coupled with evaporation into H₂O vapor. The Discrete Element Method (DEM) accounts for particle–particle and particle–wall collisions, improving realism of seed motion. Contours of H₂O mass fraction reveal zones of strong evaporation, reaching values up to 0.0026. The combined CFD–DPM–DEM approach shows how airflow, fin mixing, and collisions enhance drying efficiency.

In the Laser Cladding project, we simulated the deposition of nickel droplets under an argon gas stream using ANSYS Fluent software. The three-dimensional geometry was created in Design Modeler with a computational domain of 0.05 × 0.01 × 0.025 m. A structured non-conformal mesh was generated in ANSYS Meshing, consisting of approximately 798,400 computational cells with refined regions near the deposition zone. The transient simulation employed the VOF multiphase model, coupled with species transport and energy equations, while turbulence was modeled using the Realizable k-ε model. A User-Defined Function (UDF) implemented the moving Gaussian laser heat source, enabling realistic simulation of droplet injection, spreading, and weld layer formation.

In this project, we have simulated the thermal and airflow performance of a greenhouse with and without a heating system using ANSYS Fluent software. Three-dimensional modeling was done using Design Modeler software. The meshing of the model has been done using ANSYS Meshing software, with approximately 1,860,000 cells for the base case and 3,110,000 cells for the heated case. The energy equation, species transport, and solar ray tracing using the Discrete Ordinates (DO) radiation model are enabled for accurate representation of heat transfer and humidity. The standard K-epsilon model is selected for turbulence characteristics of fluid flow.

Co-firing Biomass with Coal Gasification. This project involves the simulation of coal and biomass co-firing in a furnace using CFD techniques. The primary objectives are to examine the combustion characteristics and validate the simulation results against the study by Ghenai and Janajreh. The furnace is defined with specific boundary conditions, and simulations are performed using an unsteady, incompressible flow model. The turbulent flow within the furnace is modeled using the k-e RNG turbulent model, thermal radiation is simulated with the P1 model, and combustion is analyzed with a PDF model. The simulation incorporates the kinetics/diffusion-limited rate model for particle combustion and the two competing rates Kobayashi model for devolatilization. Results are compared in terms of temperature contours and particle trajectories, confirming the simulation’s accuracy with a maximum error of approximately 5% in particle temperature ranges.

The report details a simulation of a Gas Turbine Can Combustor (GTCC) using Computational Fluid Dynamics (CFD) to analyze the combustion and emission characteristics of Schwarze Pumpe syngas. The setup includes a combustion system with six fuel injectors, a primary air inlet, and six secondary air inlets. The analysis uses a sophisticated mesh and applies the standard k-ε turbulence model and the P1 radiation model for accurate simulations. Key findings show that the combustor design effectively facilitates mixing and combustion, achieving a maximum inner flame temperature of approximately 1900 K. The study also successfully models pollutant formation, such as NOx, providing insights into emission control. Overall, the simulation demonstrates high combustion efficiency, supported by detailed species volume fraction contours, confirming complete fuel combustion at the outlet and the viability of the GTCC in optimizing syngas combustion processes.
