Engineering & Scientific Innovations (ESI) was tasked to document the flow within a high temperature reactor. Concerns regarding the level of fluid mixing and its impact on the level of thermal protection to the reactor wall.
Using multiple thermal anemometers the velocity field was simultaneously acquired at four locations across an air duct under cold flow conditions.
Using a computer controlled system the velocity probes were moved and complete mapping the flow as it entered the reactor was obtained.
A velocity map highlights the flow non-uniformity as fluid enters the reactor.
Although the mass flow rate was constant the degree of mixing differed depending on whether the flow was drawn or injected into the mixing duct.
