This study presents an innovative and simple way to increase the rate of heat transfer in a spiral plate heat exchanger model. Several circular cross-section rods, as continuous vortex generators, have been inserted within the spiral plate heat exchanger in the cross-stream plane. The vortex generators are located at various azimuth angles of α=30◦, 60◦, 90◦, and 120◦ with non-dimensional diame...

This paper presents generators based on decimated sequences of Generalized Feedback Shift Register (GFSR) generators. The equivalence relation between decimated GFSR generators and Tausworthe generators are presented and a k-distributed initialization scheme is derived. We present decimated GFSR generators that are maximally equidistributed. Timing results of these generators are presented.

Two types of linear congruent.ial random number generator are considered: the conventional one using integer arithmetic and another using polynomial arithmetic over finite fields. We show t.hat most of the long-period random number generators currently used or recently proposed, which include multiple re.:ursive generators, shift register generators, add-with-carry and subtract-with-borrow gene...
