Abstract | The discharge of heated water on the surface of a large body of ambient water is investigated in this study. In the first part of the work the characteristics of a two dimensional jet are considered under the presence of an imaginary boundary. It has been found that (i) The velocity decreases with an increase in the distance from the origin; (ii) The domain of influence of the imaginary boundary and the reflective velocity increase with an increase in the angle formed by the imaginary boundary with the horizontal line. In the second part, a study of the effect of the cross flow, the aspect ratio, and the densiometric Froude number in the temperature distribution of a three-dimensional jet is carried out in which the bottom slope is infinite and the surface heat loss coefficient is constant. The study shows that (i) For low values of the densiometric Froude number, the larger the values of the aspect ratio, the faster the drop in temperature is obtained; (ii) The jet depth and the jet width are respectively increasing and decreasing functions of the densiometric Froude number; and (iii) Weak cross flows do not have great effect on the temperature distribution. |
