TL;DR: In this article, a theoretical analysis of direct contact sensible heat transfer between two immiscible liquids in a countercurrent spray column is presented, and the non-dimensional parameters governing the heat transfer process are identified and a study of the effects of the variation of these parameters is made.

TL;DR: In this paper, the average volumetric heat transfer coefficient in a spray column liquid-liquid-vapour direct contact evaporator has been experimentally investigated using a cylindrical Perspex tube of diameter 10 cm and height and 150 cm.

TL;DR: In this paper, a simple mathematical model is proposed to describe the dynamic thermal behavior of a counterflow cooling tower, taking into account both the sensible and latent heat cooling effects on the tower performance.

TL;DR: In this article, the authors investigated the local volumetric heat transfer coefficient and active height of a spray column three-phase direct contact heat exchanger (evaporator) with a cylindrical Perspex tube of 100 cm height and 10 cm diameter.

TL;DR: In this article, the distribution of fluid temperatures in a direct contact heat exchanger is analyzed analytically by integration of the one-dimensional energy equations, and the influences of decisive parameters on the temperature distributions along the column are examined.

TL;DR: In this article, the temperature distribution of a liquid-liquid-vapour three-phase direct contact heat exchanger, both experimentally and theoretically, was investigated using a Perspex column with an internal diameter of 10.5 cm and 100 cm height.
