How can I design hydrothermal synthesis reactor?

Hydrothermal synthesis is simulated by coupling computational fluid dynamics with population balance modeling and appropriate reaction kinetics. Simulations indicate three distinct regimes of declining, recovering, and stable flow fields. These regimes are strongly dependent on the flow ratio between the precursor solution and supercritical water.

Hydrothermal Synthesis. References. Many sample preparation techniques require an aqueous mixture to be heated above 100°C resulting in the system having an associated vapor pressure. Examples of this are nanoparticle and zeolite synthesis. Many of these methods also require either acid or alkaline conditions where stainless steel would be readily corroded.
