The development of large power plants in Indonesia is constrained due to the development of large enough development, but nuScale small power plant is one of the alternatives that can be implemented in Indonesia because of small capital costs, unit construction is easily adjusted to the needs and already uses a passive error system and natural circulation. In addition, the accident factor is ve…
Nowadays, ozone is known as a strong oxidizing agent, so it is widely used on industrial and household scales. Ozone can be produced using the Dielectric Barrier Discharge method. This research was carried out by simulating COMSOL Multiphysics which had previously been carried out by direct ozone reactor experiments by E Yulainto et al. This reactor is cylindrical, consisting of an outer electr…
