Temperature is an important environmental factor affecting streamer discharge. However, the mechanism and regularity of influence are still unclear. This paper analyzes how parameters in hydrodynamic model affected by temperature finite element method used to solve three particle continuity equations along with Poisson’s equation simultaneously. The results show that increase inhibits ionizatio...

The mystacial vibrissae of harbour seals (Phoca vitulina) constitute a highly sensitive hydrodynamic receptor system enabling the seals to detect and follow hydrodynamic trails. In the wild, hydrodynamic trails, as generated by swimming fish, consist of cyclic burst-and-glide phases, associated with various differences in the physical parameters of the trail. Here, we investigated the impact of...

The effects resulting from coupling between translational and rotational diffusion on electro-optical transients were analyzed by Brownian dynamics simulations. Diffusion tensors, including translational-rotational coupling tensors, were derived from bead model simulations. Optical and electrical parameters were assigned according to models and experimental data. Hydrodynamic coupling has a str...

Hydrodynamic instabilities in one-dimensional electron flow in semiconductor and their dependency with the electron and lattice temperatures are studied here. The driving force for the electrons is imposed by a voltage difference, and the hydrodynamic and electrostatic equations are linearized with respect to the steady-flow solution. A two-temperature hydrodynamic model predicts a stable elect...

asphaltene precipitation and deposition is a serious problem in many iranian fields. the deposited asphaltene results in partial or total blockage of the wellbore and wellstring reducing or completely seizing oil production. this paper studies the asphaltene problem and mitigation methods in wellstring systematically. it presents new approach based on the combination of thermodynamic modeling o...

muskingum-cunge is one of the widely employed methods for flood routing. direct calibration of the model based on previous flood events is not required and the routing parameters in this method are determined according to physical characteristics and hydraulic conditions of the stream. during the last decade, different modifications were proposed for the method to increase its accuracy. in this...
