This report presents a simulation which investigates the production of hydrogen gas from ammonia, using the heat of the propane-air reaction. The ammonia conversion rate and the overall system efficiency were calculated. The geometry of the ammonia decomposition micro-combustor was created using ANSYS SpaceClaim software. A high-quality tetrahedron elements mesh was generated using ANSYS Meshing software. Appropriate species transport settings and boundary conditions were applied to correctly simulate the rate of ammonia decomposition.

This project aimed to simulate the performance of a heat pump dryer designed for drying wet wood volatiles. The Volume of Fluid (VOF) method was employed to capture the interaction between air and liquid water phases. Species Transport Model was activated to simulate the mass transfer associated with water evaporation. A User-Defined Function (UDF) was developed to represent the evaporation process accurately.

Comprehensive analysis of different CFD algorithms using a variable-width channel case study (5cm inlet, 10cm outlet, 20cm length). Pressure-based solvers (SIMPLE, SIMPLEC, PISO, Coupled) compared with density-based solvers (Roe, AUSM) for various flow conditions. SIMPLE algorithm excels in low-speed flows, while Coupled solver shows superior performance across all speed regimes. Density-based solvers (Roe, AUSM) perform best in high-speed and supersonic flows but struggle with low Mach numbers. Under-relaxation factors significantly impact convergence stability and simulation accuracy. Optimal solver selection depends on flow regime: low subsonic (SIMPLE/SIMPLEC), transonic/supersonic (Coupled/AUSM), hypersonic (Roe/AUSM).

Discretization methods in ANSYS Fluent are crucial techniques for converting continuous fluid flow equations into solvable numerical forms. Three main gradient calculation methods are available: Green-Gauss Cell-Based, Green-Gauss Node-Based, and Least Squares Cell-Based. Pressure discretization offers five options: Second-Order, Standard, PRESTO, Linear, and Body Force Weighted schemes. Momentum discretization includes First-Order Upwind, Second-Order Upwind, QUICK, and MUSCL schemes. Choice of method depends on mesh quality, required accuracy, and available computational resources. These methods apply to various parameters including pressure, velocity, energy, turbulence, and species transport equations.
