A rolling piston engine, operating according to a novel thermodynamic cycle is designed. Thermodynamic and structural analysis of this novel engine is carried out and thermodynamic and structural variables of the engine were calculated. The losses in the engine, friction and leakage were calculated and their effects on the engine were demonstrated.

Thermodynamic and structural design and analysis of a novel turbo rotary engine
Ercan, Taylan; Akmandor, İbrahim Sinan; Department of Aerospace Engineering (2005)
A novel turbo rotary engine, operating according to a novel thermodynamic cycle, having an efficient compression phase, a limited temperature combustion phase followed by a long power extraction phase is designed. Thermodynamic and structural design and analysis of this novel engine is carried out and two prototypes are manufactured according to these analysis. High performance figures such as torque, power and low specific fuel consumption are calculated. Also the component tests of the manufactured protot...
Performance evaluation of a wind driven DOIG using a hybrid model
Cadirci, I; Ermiş, Muammer (1998-06-01)
This paper presents the performance analysis of a wind driven double output induction generator (DOIG) operating at varying shaft speeds. A periodic transient state analysis of DOIG equipped with two controlled converters is carried out using a hybrid induction machine model. It is shown that practical aspects of converters such as overlap and harmonics reduce the power output of the DOIG system and limit the operating shaft speed range, especially in the subsynchronous region near the synchronous speed. Va...
DYNAMIC ANALYSIS OF GEARED ROTORS BY FINITE-ELEMENTS
KAHRAMAN, A; Özgüven, Hasan Nevzat; HOUSER, DR; ZAKRAJSEK, JJ (1992-09-01)
A finite element model of a geared rotor system on flexible bearings has been developed. The model includes the rotary inertia of shaft elements, the axial loading on shafts, flexibility and damping of bearings, material damping of shafts and the stiffness and the damping of gear mesh. The coupling between the torsional and transverse vibrations of gears were considered in the model. A constant mesh stiffness was assumed. The analysis procedure can be used for forced vibration analysis of geared rotors by c...
Aerodynamic shape optimization of wind turbine blades for minimizing power production losses due to icing
Yirtici, Ozcan; Tuncer, İsmail Hakkı (2021-05-01)
Ice formation on a wind turbine alters the airfoil profiles of the blades and causes degradation in the aerodynamic performance of the wind turbine and the resulting power production losses. Since the blade profile plays a significant role in the icing of a blade, power production losses due to icing can be minimized by optimizing the blade profile against icing. In this study, blade profiles are optimized in order to minimize power production losses. A Gradient based aerodynamic shape optimization method i...
Design optimization of variable frequency driven three-phase induction motors
Ertan, B; Leblebicioğlu, Mehmet Kemal; Simsir, B; Hamarat, S; Cekic, A; Pirgaip, M (1998-01-01)
An approach to optimize the design of three-phase induction motors for a wide speed range drive is considered. Two operating points in the speed range are taken into consideration. The problem is handled as a constrained optimization problem. An accurate model for the motor in terms of its dimensions has been developed which predicts the motor performance based on about 60 parameters of motor geometry.
