Abstract
This paper presents a computational technique capable of simulating threedimensional
flows involving stationary or moving boundaries on fixed grid. This
method relies on finite-difference schemes for the flow governing equations and
a level-set method to track the embedded boundaries. The mesh points adjoining
the interface are subjected to special treatment to capture the immersed interface
without smearing. The results of the accuracy studies indicate that the accuracy
is not compromised in adopting finite-difference schemes instead of finitevolume
methods. Several two- and three-dimensional flows simulated for
validation show that the current method compares well with the benchmark
results for a variety of problems.
