RECTANGULAR SURFACE

The PCM algorithm is as follows. First, the cavity siuface is determined from the van der Waals radii of the atoms. That fraction of each atom s van der Waals sphere which contributes to the cavity is then divided into a nmnber of small surface elements of calculable surface area. The simplest way to to this is to define a local polar coordinate frame at tlie centre of each atom s van der Waals sphere and to use fixed increments of AO and A(p to give rectangular surface elements (Figure 11.22). The surface can also be divided using tessellation methods [Paschual-Ahuir d al. 1987]. An initial value of the point charge for each surface element is then calculated from the electric field gradient due to the solute alone ...

Measuring the area of the film is less troublesome. If the edges of the tray are parallel and the barriers perpendicular to them, the area of the rectangular surface is easily determined. The curvature of the surface at the hydrophobic boundaries introduces a small error but — since the total area is of the order of magnitude of 10 2 m2—this is generally negligible.

Problem Consider an elemental surface dA and a finite rectangular surface A2 which are parallel to each other and positioned as shown in the figure above. Surface dAi is parallel to the xy plane and positioned on the oy axis at a distance d from the origin. Surface A2 has one comer at the oz axis, and its sides a and b are parallel to the ox and oy axes, respectively. Find the diffuse view factor re-... 

The average heat-transfer coefficient from horizontal flat plates is calculated with Eq. (7-25) and the constants given in Table 7-1. The characteristic dimension for use with these relations has traditionally [4] been taken as the length of a side for a square, the mean of the two dimensions for a rectangular surface, and 0.9d for a circular disk. References 52 and 53 indicate that better agreement with experimental data can be achieved by calculating the characteristic dimension with...
