Several studies have been carried out by Barata et al [1] on the turbulence characteristics of a jet impacting a flat surface in the presence of a transverse flow by varying the jet Reynolds number between 60,000 to 120,000.Klein [2] studied the influence of the Reynolds number on the behavior of a plane jet.
Recker et al [3] carried out an experimental study for a round jet on a transverse flow with a weak momentum ratior=Pj.Uj2P∞.U∞2=1 and a Reynolds number Re = 1600.
Barata et al [6] studied experimentally two impinging jets aligned with a cross-flow.
Guo et al [11] numerically studied the velocity and turbulent kinetic energy for a lateral jet in cross flow by varying Vj / U0 = 1, 2 and 4.

Mitsak et al. (2011) [15] pointed out that that the minimum compressive strength for scaffolds used in bone regeneration is 2 MPa, which is below that of the RP scaffolds.

Bertsimas et al. compute directions pointing away from all worst-case realizers and show that such directions are descent directions for the (unconstrained) robust counterpart, which is a minimax problem [6].

Bhatti et al
Recently, Farooq and Lin [66], Farooq et al. [67] and Farooq et al. [68] have successfully applied BVPh 2.0 to different nano-fluids problems.
Here we have revisited the problem tackled by Bhatti et al. [45] by including thermal radiation.
In Tables 3 and 4, the local skin friction coefficient f''(0) for different values of α1 are seen to be in excellent agreement with those reported by Wang [25], Mahapatra et al. [36], Fan et al. [30] and Kumar and Sood [42].
