Study on the fluid dynamics of nitrogen and hydrogen gases subjected to wires element in monolithic channel

Ammonia has a very significant value in the fertilizer industry where it was being synthesized via Haber-Bosch process in the early 19th century. As the process utilize high operating conditions, it imposes high capital cost and is an energy-consuming process. Due to this unsustainable process, rese...
