Detailed Description

Inherits from InsertionBoundary Some images are useful to better understand the structure of both the hopper-chute combination, as of the hopper insertion boundary itself:

Image clarifying the definitions of the data members hopperLength_, hopperExitLength, hopperHeight_ and hopperAngle_.

Image shows the AC and AB directions used to determine a particle position inside the hopper. NB: the X and Z directions are in the same plane, but pointed along the chute and normal to the chute, respectively.

Todo:

(BvdH) Better graphical diagrams are needed for further clarification, as well as some property renaming.

placeParticle()

void HopperInsertionBoundary::placeParticle ( BaseParticle *  p, RNG &  random  )

overridevirtual

This places an inflow particle in the top 50% of the hopper i.e. between gamma=0.5 and gamma=1.0.

This function places random particles inside the hopper. The space in which the particles are placed in a (truncated) triangle in 2D, or a (truncated) pyramid in 3D. Some aspects of the hopper geometry and definitions which are useful in order to understand this particle placement code are:

• In the hopper simulation, the direction of the CHUTE is defined to be the X-direction, while the normal of the chute is defined to be the Z-direction. This means that gravity is NOT in the negative Z-direction, but is actually on an angle w.r.t. the X and Z axes. NB: AC and AB are unit vectors in the direction of negative gravity and the 'normal' horizontal plane, respectively.
• The third dimensional direction, which points into the plane spanned by the X and Z directions, or the AC and AB directions alternatively, is equal for either of the two definitions. Ergo, AD = the unit vector in the Y-direction. This dimension is not used in the 2D case.
• The hopper is filled with particles from the base of the inverted triangle/pyramid (which defines the upper part of the hopper) down to a certain percentage fillPercent_ of the hopper depth. fillPercent_=100 will fill entire inverted triangle/pyramid down to it tip (position A). 'gamma' is the random height between the base and given fillPercent_ at which the particle is placed. NB: 'down' in this case means negative AC (vertical) direction.

See also the images provided at the top of this class' documentation.

Todo:

Parameters

[in]

random

random number generator

Returns

pointer to the particle generated

Bram: Where does the '40' come from??

The 'one-dimensional' hopper has sloped walls in the AB extrema, while the walls in the AD (Y) extrema are vertical. 'delta' is the randomly generated Y-position of the particle and lies between yMin_ and yMax_ (with a particle radius distance from the extrema on either side).

Bug:

for periodic walls this should be only minus one particle radius, this should be fixed at some point. Thomas' response: using one particle radius gives problems when the wall is not orthogonal to the y-direction; the distance has to be slightly higher than one; if you can figure out the exact value, then correct it please.

Todo:

Thomas, could you check if this bug is still valid? (BvdH)

The 'two-dimensional' hopper has sloped walls in the extrema of both (horizontal) AB and AD directions. I.e., the HopperInsertionBoundary has the form of an inverted (and possibly truncated) pyramid. The possible Y-positions of the generated particle (i.e. delta) in this case is dependent of both the vertical AC-position gamma, and the hopper angle (in this case in the form of its cosine, Hc).

hopperExitLength_

double HopperInsertionBoundary::hopperExitLength_

The horizontal (AB-direction) width at the square exit of the hopper.

hopperHeight_

double HopperInsertionBoundary::hopperHeight_

The vertical (AC-direction) height of the hopper, measured from the top of the hopper to the start of the chute.

yMax_

yMin_

double HopperInsertionBoundary::yMin_

The minimum and maximum y-positions of the particle for a hopper with vertical walls in the y-direction ('1D hopper'). For the '2D hopper', these variables have no physical meaning, except for the fact that the insertion boundary is centered in the y-direction at (yMax_ - yMin_)/2 .
