The improvement of combustion process and reduction of unburned hydrocarbon emission in a two-stroke motorcycle
(Shiraz University, 2004-02-01)In desert areas in which there are few asphalt roads, heavy vehicles can not commute easily. Two-stroke motorcycles are lighter and have higher output power in comparison with similar four-stroke ones. In the present ...

An analysis of shear correction factors in a thermoplastic composite cantilever beam
(Shiraz University, 2004-02-01)In the present study, an analysis of shear correction factors is carried out for a homogeneous polyethylene thermoplastic cantilever beam which is reinforced by steel fibers with a rectangular cross-section. An applied ...

Pressure-based compressible calculation method utilizing normalized variable diagram scheme
(Shiraz University, 2004-02-01)A pressure-based implicit procedure to solve the Euler and Navier-Stokes equations on a nonorthogonal mesh with collocated finite-volume formulation is described. The boundedness criteria for this procedure are determined ...

Generalized line-of-sight guidance with lead angle
(Shiraz University, 2004-02-01)A generalized three-dimensional line-of-sight guidance with a lead angle (GLOS) is presented for maneuvering targets. In the proposed guidance law, we define a desired line-of-sight (LOS) from the tracker by taking the ...

The LES and DNS simulations of heat transfer and fluid flow in a plate-fin heat exchanger with vortex generators
(Shiraz University, 2004-02-01)Unsteady three-dimensional DNS and LES simulations for resolutions up to about 1.2 million points were performed to investigate the fluid flow and heat transfer in a plate-fin heat exchanger with vortex generators. The ...

3D thermo-viscoplastic modeling of welds: effect of piece-wise welding on thermo-mechanical response of thick plate weldments
(Shiraz University, 2004-02-01)The effect of piece-wise welding on thermal and mechanical response of thick plate weldments is studied by the use of a 3-D thermo-viscoplastic model. Anand's viscoplastic model is used to simulate the rate dependent plastic ...

Stagnation flow and heat transfer on a moving cylinder with transpiration and high Reynolds numbers consideration
(Shiraz University, 2004-02-01)High-Reynolds-number unsteady viscous flow and heat transfer in the vicinity of an axisymmetric stagnation point of an infinite moving cylinder with time-dependent axial velocity and with uniform transpiration, , is ...

On stability of the column with a step change in a cross section
(Shiraz University, 2004-02-01)Stability of an elastic column with a changeable cross section loaded by a concentrated force of arbitrary intensity is studied. It is assumed that the column is fixed to a rigid circular plate that is positioned on a ...

A biomechanical model to analyze normal, degenerated, and fused cervical spines using IAR’s concept
(Shiraz University, 2004-02-01)During voluntary flexion/extension of the head-neck system, the cervical spine undergoes a stepwise motion from upper to lower regions with a specific pattern. The motion of each vertebra is composed of a translation and ...

Performance comparison between planing monohull and catamran at high Froude numbers
(Shiraz University, 2004-02-01)Conventional ships have been used for many years with usual body forms. But recent developments in high speed crafts have created many different alternatives. Therefore the selection of hull type becomes an important issue ...

Comparison of different control strategies on a vehicle using sliding mode control
(Shiraz University, 2004-02-01)In this study, the vibration control of a half vehicle model with a passenger seat using a sliding mode control is considered. Three cases are taken into account as the control strategies. First, the model having passive ...
