Estimating Sweet Spot for UAV Formation Flight Using Vortex Lattice Method and Machine Learning Tatar, Umutcan; Kahveci, Harika Senem (2023-09-15)
Numerical Simulation of Spray Characteristics of Doublet Injectors Gulmez, Senem; Kahveci, Harika Senem (2021-09-30)
Investigation of a rotor blade with tip cooling subject to a nonuniform temperature profile Kahveci, Harika Senem (2021-07-01) One of the challenges in the design of a high-pressure turbine blade is that a considerable amount of cooling is required so that the blade can survive high temperature levels during engine operation. Another challenge is ...
Effect of Turbine Blade Tip Cooling Configuration on Tip Leakage Flow and Heat Transfer Sakaoglu, Sergen; Kahveci, Harika Senem (ASME International, 2020-02-01) The pressure difference between suction and pressure sides of a turbine blade leads to tip leakage flow, which adversely affects the first-stage high-pressure (HP) turbine blade tip aerodynamics. In modern gas turbines, HP...

Effect of turbulence modeling for the prediction of flow and heat transfer in rotorcraft avionics bay Akin, Altug; Kahveci, Harika Senem (Elsevier BV, 2019-12-01) In this paper, four turbulence models are compared on the basis of the predictions they produce for the flow and heat transfer in the avionics bay area of a rotorcraft. The turbulence models studied are the standard k-s, R...
Effect of cavity depth on thermal performance of a cooled blade tip under rotation Sakaoglu, Sergen; Kahveci, Harika Senem (2019-11-01) In this paper, the effect of cavity geometry of a squealer blade tip on its thermal performance is investigated. Numerical analyses were performed for three depth-to-width ratios for a cooled squealer tip. Also investigate...
Gas Turbine Blade Cooling Technology, Advances, and Challenges Kahveci, Harika Senem (null; 2019-09-30) Continuous advances in cooling technologies have become necessary since the engine thermal efficiency and power output increase significantly with an increase in the turbine inlet temperature. This study explains blade coo...
An optimization study for rotorcraft avionics bay cooling Akin, Altug; Kahveci, Harika Senem (2019-07-01) In this paper, a computational investigation of a rotorcraft avionics-bay cooling system is carried out. The introduced avionics cooling system utilizes a forced-convection method in which the ambient air is supplied to th...
Use of artificial neural network in rotorcraft cooling system Akin, Altug; Kahveci, Harika Senem (2019-07-01) In this study, an Artificial Neural Network (ANN) is used to determine the surface temperatures of the avionics equipment located in an avionics bay of a rotorcraft. The bay is cooled via a system of a fan that supplies am...
