The present study describes the adjoint based shape optimization of sub-merged trapezoidal intake. Initially direct results on the baseline geometries are compared with published results which are found to be in good agreement. Thereafter study proceeds to shape optimization using as multiobjective optimization technique. The combined multi-objective objective function is employed, comprising of total pressure at AIP and lift of the aerodynamic body. The inherent shape of the sub-merged intake gives low drag but also low-pressure recovery, therefore lift as an additional objective can give advantage over other intake types. The study is performed using SU2 the flow solver together with the built-in adjoint solver and the FFD box which is the shape deformation tool in a parallel computing environment. A reduction in total pressure loss of 10% was achieved at AIP while CL/CD increased for the overall body.

Adjoint Based Aerodynamic Shape Optimization of Subsonic Submerged Intake AHMED, ALI; Tuncer, İsmail Hakkı; Department of Aerospace Engineering (2021-5-04) In this study the aerodynamic shape optimization of subsonic submerged intake is performed. The total pressure at the aerodynamic interface plane and lift are employed as objective functions. Drag is constrained and employed as penalty objective. Open-ware platforms are used including SALOME for solid modeling, GMSH for the hybrid mesh generation and SU2 for flow solutions and adjoint based shape optimization. Free form deformation box is employed for shape parameterization and surface deformation. Ini...
ADJOINT BASED SHAPE OPTIMIZATION OF SEMI-SUBMERGED INLETS AND DEVELOPMENT OF A NOVEL BOUNDARY LAYER DIVERTER Küçük, Umut Can; Tuncer, İsmail Hakkı; Department of Aerospace Engineering (2022-12-28) In this study, boundary layer ingesting and diverting submerged air inlets are design optimized with an adjoint-based optimization methodology based on RANS solu tions. The opensource SU2 software is employed for both RANS and adjoint solutions and for driving the gradient-based optimization. Total pressure recovery at the aerodynamic interface plane is taken as the main objective of the optimization, and the mass flow rate and the momentum distortion are closely monitored. It is first shown that the shape ...
Computation of Vortical Flow Fields over a Close-Coupled Delta Canard-Wing Configuration and Adjoint Based Configuration Optimization Tikenoğulları, Alp; Tuncer, İsmail Hakkı; Department of Aerospace Engineering (2022-2-10) This study aims at investigating the vortical flow field over a close-coupled delta canard-wing configuration to understand the vortex interactions and the mechanism of lift enhancement provided by the canard, especially at high angles of attack, and employing an adjoint-based configuration optimization to achieve further enhancements in aerodynamic forces. An open-source CFD solver, SU2 is employed for both flow field computations and adjoint-based configuration optimizations. First, flow solutions with SU...
Experimental evaluation of geomembrane/geotextile interface as base isolating system Kalpakci, V.; Bonab, A. T.; Özkan, M. Yener; Gülerce, Zeynep (Thomas Telford Ltd., 2018-02-01) The objective of this study is to evaluate the effect of the geomembrane/geotextile interface on the seismic response of small-to-moderate height structures. Three building models with first-mode natural frequencies changing between 2-4 Hz (representing two, three and four storey structures) were tested with and without the addition of geomembrane/geotextile interface using the shaking table test setup by employing harmonic and modified/ scaled ground motions. Experimental results showed that the geomembran...
Ground Motion Prediction Equations for the Vertical Ground Motion Component Based on the NGA-W2 Database Gülerce, Zeynep; Abrahamson, Norman A.; Silva, Walter J. (SAGE Publications, 2017-05-01) Empirical ground motion models for the vertical component from shallow crustal earthquakes in active tectonic regions are derived using the PEER NGA-West2 database. The model is applicable to magnitudes 3.0-8.0, distances of 0-300 km, and spectral periods of 0-10 s. The model input parameters are the same as used by Abrahamson et al. (2014) except that the nonlinear site response and depth to bedrock effects are evaluated but found to be insignificant. Regional differences in large distance attenuation and ...
