AB  - The effect of surface curvature, number of jets, number of jet rows, jet arrangement, crossflow, and surface motion on the heat transfer and pressure 
force performance from multiple impinging round jets on the moving flat and curved surface have been numerically evaluated. The more number of 
jets (more than three jets) has no significant effect on the average heat transfer rate. The more number of jet rows increases the strength of wall jets 
interference and crossflow effects and degrade the average heat transfer rates. There is a minor difference between inline and staggered arrangements 
on both moving flat and curved surfaces. The surface motion has a stronger effect on the impinging jets in the intermediate crossflow scheme than in 
the minimum crossflow scheme. The total average Nu on both moving flat and curved surfaces reduces with an increase in the velocity ratio and surface 
curvature. The pressure force is relatively insensitive to the surface motion on both moving flat and curved surfaces.
