Analysis of Laminar Film Condensation on a Vertical Plate

Periodic Wave Shock solutions of Burgers equations

In this paper we investigate the exact peroidic wave shock solutions of the Burgers equations. Our purpose is to describe the asymptotic behavior of the solution in the cauchy problem for viscid equation with small parametr ε and to discuss in particular the case of periodic wave shock. We show that the solution of this problem approaches the shock type solution for the cauchy problem of the in...

Ignition of Aluminum Particle Clouds Behind Reflected Shock Waves

Extending on a companion paper in this colloquium, the dispersion, ignition and combustion characteristics of aluminum particle clouds is investigated numerically behind reflected shock waves. It is observed that a higher proportion of the Al cloud by mass burns for a higher initial cloud concentration. Vorticity from the cloud wake and from that deposited by the reflected shock cause the parti...

Numerical and Analytical Approach for Film Condensation on Different Forms of Surfaces

This paper tries to achieve a solution for problems that concern condensation around a flat plate, circular and elliptical tube in by numerical and analytical methods. Also, it calculates entropy production rates. At first, a problem was solved with mesh dynamic and rational assumptions; next it was compared with the numerical solution that the result had acceptable errors. An additional suppor...

Determination of Shock Standoff Distance for Wedge at Supersonic Flow

An experimental investigation is conducted to calculate the shock standoff (SSO) distance in front of an acute-angled wedge. For this experimentation, simple water flows channel analysis is carried out. The flow velocity is varied from 13.2 cm/s to 25.5 cm/s increasing in steps of 1 cm/s. A velocity of 13.2 cm/s corresponds to Froude number 1.13 and velocity of 25.5 cm/s to Froude number 1.41. ...
