TLDR
In this paper, the authors measured the transfer coefficients resulting from the impingement of a slot jet on a plane surface using naphthalene sublimation technique and found that the surface distributions of the transfer coefficient were bell-shaped, with the largest value at the stagnation point.About:

Unsteady heat transfer analysis of an impinging jet
Yongmann M. Chung,Kai H. Luo +1 more
TL;DR: In this article, the authors studied the effect of a confined impinging jet on the heat transfer in the Navier-Stokes equations and found that the instantaneous flow fields and heat transfer distributions are highly unsteady and oscillatory in nature.

Local heat transfer to impinging liquid jets in the initially laminar, transitional, and turbulent regimes
Bret P. Elison,Brent W. Webb +1 more
TL;DR: In this article, the Nusselt number was observed to correlate approximately with Re 0.5 and Re 1.8 for initially turbulent and laminar jets, respectively, for both free-surface and submerged jet configurations.

The role of turbulence in determining the heat-transfer characteristics of impinging jets
Robert Gardon,J. Cahit Akfirat +1 more
TL;DR: In this paper, it was shown that some seemingly anomalous heat transfer phenomena can be explained as effects of the intense and spatially varying turbulence inherent in jets, which can be used to explain the heat transfer properties of impinging jets.

Diffusion of Submerged Jets
TL;DR: As the direct result of turbulence generated at the borders of a submerged jet, the fluid within the jet will undergo both lateral diffusion and deceleration, and at the same time fluid from the su...
