Abstract
Non-uniform flow caused due to a vortex in the pump intake is considered undesirable for highly efficient and low maintenance operation. Sometime due to improper design or complex flow condition, this problem becomes unavoidable. Hence, there is a need to characterize such condition. Performing experiment is not feasible on conventional setup; hence, experiments with scale models have been done to assess the performance of the pump. Such tests are expensive and time consuming and thus there is a need of alternative computation fluid dynamics (CFD) methods. By referring to some of the benchmark experimental results [1], we have analyzed the performance of different turbulent models available with fluent 15.0 for steady state and transient state single-phase operation. Results of k−ω, LES (Large eddy simulation), and DES (Detached eddy simulation) models have been generated and compared with the benchmark result [1].
