This paper focus on the detailed influence of forward-facing cavity on the opposing jet. The flow field of a hemisphere nose-tip with the combined configuration was simulated numerically and the surface heat flux distribution was obtained. The numerical results show that a suitable cavity is helpful for the opposing jet. With the same total pressure, the single opposing jet even can’t form a stable flow field and there is no cooling effect.

In this paper, three kinds of mathematical models of cable heated radiant floors were established, and numerical simulation of heat transfer process for these heated floors were carried on by using finite element method and ANSYS software. The rule of temperature distribution, surface heat flux distribution and downward heat loss of these three floor structures were given and compared. The results can provide references for a further optimization, design and application of low temperature radiant heating floor.
