Based on the concept of artificial pressure, the APPLE (Artificial Pressure for Pressure-Linked Equation) and the NAPPLE (Nonstaggered APPLE) algorithms are developed for incompressible flows. Through two well-known examples, the APPLE algorithm is found to produce essentially the same results with only about 40 \% CPU time as compared with the SIMPLER algorithm. Due to its simplicity, the NAPPLE algorithm has a potential use for problems with arbitrarily shaped domain as long as the grid size is not large.
