Abstract

Urea (NH2CONH2) as fertilizer is important for agriculture industry. Potential one step urea synthesis patent based on magnetically induced process can bypass ammonia step by reacting H2, N2, and CO2 directly at ambient temperature and pressure. At current state, the design of microreactor for one step urea synthesis is not available. The fluid flow of the gases for ammonia synthesis is simulated using in Computational Fluid Dynamics (CFD) approach. This study addressed the gap by focusing on finding the optimum microchannel design for the microreactor by varying geometry design. Mesh sensitivity study is performed to ensure acceptable results. In the microchannel where the scale is between micrometer to nanometer, the mesh quality can be reached by varying number of nodes in every geometry design. Investigating mesh quality can be obtained by measuring element quality, using Richardson Extrapolation method and Grid Convergence Index. The accepted mesh quality of most the geometry design is between 900,000 and 1,300,000 elements.
