R&D

The SOLDES project focused on developing and optimizing solar-powered desalination technologies. Simtec created a CFD model using Ansys Fluent to simulate the operation of a pad humidifier, a key component in the desalination process. The model, based on a prototype designed by the Agricultural University of Athens, helped engineers evaluate the mass and heat transfer phenomena, aiding in the design of an industrial-scale unit.

The project involved developing a CFD model in Ansys Fluent to improve the performance of Electrostatic Precipitators (ESPs) for particulate removal from flue gas. Simtec extended the solver with custom code to handle the electrostatic characteristics of ESPs, modeling gas flow, particle dynamics, and electrostatics. The model provided insights into particle behavior near charged wires and helped optimize ESP performance through detailed parametric analysis.

The project involved developing a mathematical model to simulate low-temperature solid fuel carbonization in an industrial rotary kiln reactor. Simtec customized Ansys Fluent to model fuel drying, devolatilization, and char gasification, solving for reactions between gas and solid phases. The simulations provided detailed insights into reaction rates, phase velocities, and concentrations, aiding in optimizing the carbonization process.

The project focused on developing a CFD model for the deNOx process in a Fluid Catalytic Cracking (FCC) regenerator to reduce NOx emissions. Simtec used Ansys Fluent and Chemkin to simulate gas-solid flow and detailed gas phase reactions, achieving the first successful multiphase CFD simulation of an FCC regenerator with advanced chemistry modeling.

The project developed a simulation method to assess vehicle emission control systems' durability during design. Using Axisuite® and Ansys Fluent, it evaluated emissions reduction over the system's lifespan, leading to new software and methodologies for optimizing pollution control.

The project created a CFD code to simulate blade rotation in a paddlewheel flow meter, focusing on optimizing industrial mixing processes in single-phase and two-phase flows. The simulations were validated with experimental data, using Ansys Fluent.

The project aims to enhance 3D Intravascular Ultrasound (IVUS) analysis for detecting coronary plaque. It developed an automated system integrating IVUS and angiography data to create 3D artery models. These models support CFD simulations to analyze blood flow, aiding clinical diagnosis, using Ansys Fluent.

Methanol production from CO and CO2 in a plug flow reactor was studied using Ansys Fluent. The study incorporated catalytic reactions and the water gas shift reaction, with zeolite particles introduced to enhance methanol yield.
