The aerodynamic characteristics directly affect driving characteristics, stability, operation, oil consumption, and safety of automobiles. The aerodynamic analyses of automobiles, such as the virtual wind tunnel experiment simulation, based on finite element methods have provided useful theoretical reference to automobile bodywork design. In this study, the air flow vector variation and distrib...

electric vehicles (evs) have gained the attention of many authorities, automakers and researchers due to their considerable energy saving and emission reduction. one of the main issues that must be considered in design of a road vehicle is the calculation of aerodynamic forces. this issue also must be scrutinized in the design of evs. installation of rear spoiler is one of the solutions propose...

a knowledge of physical and aerodynamic properties of agricultural crops is important and essentially required for the design and development of a crop's harvesting and post-harvesting equipments. in the present research, experiments were conducted to determine physical and aerodynamic properties of fars province pinto bean namely: kernel size and shape (length, width, thickness, projected...

Characterization of an off-the-shelf small tailless aircraft with a wing span of 1.3m is presented. Mentioned aircraft is being used in several scientific measurement projects by authors, whereas the flight performance and quality such as endurance, and stability plays an important role on the measurement quality. Hence the main objective is to use the extracted and fine tuned aerodynamic and f...

A waveform adaptive physical model of the glottal source is proposed. The model relies on a lumped mechano aerodynamic schema loosely inspired to the oneand two-mass lumped models. The vocal folds are represented by a single mechanical resonator and a propagation line which takes into account the vertical phase differences. The vocal folds displacement is coupled to the glottal flow by means of...
