This is followed by applying this solver to predict the jet in cross flow phenomena. Another main objective for this study is to reveal the flow details and flow instability by rigorously analyzing the simulated vector field following the topological and bifurcation theories.沉浸邊界法不規則網格橫向流與射流拓撲與分岔理論不穩定現象irregular domainparallel environmentimmersed boundary methodinstabilitytopological and bifurcation theories
