v = masses[index]->getVel();//get the velocity v.y = 0;//omit the velocity component in y direction //The velocity in y direction is omited because we will apply a friction force to create //a sliding effect. Sliding is parallel to the ground. Velocity in y direction will be use...
5.Concentration gradient dc/db, where b is the length of the path perpendicular to the area across which diffusion is occurring. Appropriate subscripts are used when needed. 9 (3)Velocities in diffusion(扩散速率) ?Velocity without qualification refers to the velocity relative to the interface ...
The above indicates that thevelocity fieldfor anincompressible fluidis a solenoidal field, that is a field in which the divergence of the considered variable is equal to zero at all points in space. View chapterExplore book Status and research trends of direct alcohol fuel cell technology ...

Here ϵ, v, ρ, and S denote porosity, velocity, gas density, and mass sources due to a transition from phases and their reactions (Peters, 2011). It's an essential aspect of the particle model to figure out what's happening in real-time. The primary goal is to focus on the criti...
First, it is possible to imagine the existence of objects with such a large mass that the escape velocity for objects to escape the gravitational attraction of such an object will be equal to the speed of light. Consequently, no information from this object will get to the outside world....
The collection and analysis of air samples for the study of microbial airborne communities or the detection of airborne pathogens is one of the few insights that we can grasp of a continuously moving flux of microorganisms from their sources to their sin
Two equal masses travelling at velocities of 4 m/s and -2 m/s collide by direct impact and stick together. What is the velocity of the combined masses following the collision? When a compound is separated, is this a chemical...
v is the fluid velocity, cm/s. R is the hydraulic radius, υ is the viscosity coefficient of fluid, m2/s. The model with non-equal width ratio fillings is simplified to Fig. 5. The seepage inlet is the end with larger filling width, the filling width at the inlet and outlet areei...
a, The probability of retaining a bound tertiary as a function of the kick velocity in the inner binary. In general, this probability diminishes at large kicks because these are only allowed when the tertiary originates in a tight orbit and must be fine-tuned to be large enough to send it...
