Steady collision of two jets issuing from two axially symmetric channels

Lili Du, Yongfu Wang

In the classical survey (Chapter 16.2, {\it Mathematics in industrial problem}, Vol. 24, Springer-Verlag, New York, 1989), A. Friedman proposed an open problem on the collision of…

Oblique Injection of incompressible ideal fluid from a slot into a free stream

Jianfeng Cheng, Lili Du

This paper deals with a two-phase fluid free boundary problem in a slot-film cooling. We give two well-posedness results on the existence and uniqueness of the incompressible invis…

Existence and uniqueness of axially symmetric compressible subsonic jet impinging on an infinite wall

Jianfeng Cheng, Lili Du, Qin Zhang

This paper is concerned with the well-posedness theory of the impact of a subsonic axially symmetric jet emerging from a semi-infinitely long nozzle, onto a rigid wall. The fluid m…

A free boundary problem for semi-linear elliptic equation and its applications

Jianfeng Cheng, Lili Du

In this paper, we consider a free boundary problem of a semilinear nonhomogeneous elliptic equation with Bernoulli's type free boundary. The existence and regularity of the solutio…

Incompressible impinging jet flow with gravity

Jianfeng Cheng, Lili Du, Zhouping Xin

In this paper, we investigate steady two-dimensional free-surface flows of an inviscid and incompressible fluid emerging from a nozzle, falling under gravity and impinging onto a h…
