Abstract
A three-dimensional unstructured finite-volume method is used to investigate laminar flow characteristics of a miniature chamber with a possible application to micro gas turbine combustor design. The chamber is cylindrical in shape and a baffle plate is installed at its entrance having one fuel jet located at the center and six oxidizer jets deployed to surround the fuel jet. Attention is given to the effect of the inlet conditions on the flow structure and mixing pattern inside the chamber. Computations are carried out with the calculation domain inlet being positioned at two different locations. Numerous inlet conditions are examined including 'top-hat', fully-developed, swirling, annular backward-facing step and some asymmetrically skewed profiles. The baffle plate is shown to have a significant smoothing effect on the inlet conditions for a Reynolds number of 100. However, for larger Reynolds number, the flow stability is more sensitive to the upstream conditions. In some cases, asymmetric profiles are obtained downstream of the baffle plate.
