Authors: Avramenko A.A. , Tyriniv A.I. , Dmitrenko N.P. , Kovetska M.M. 
Published: December 2022

Boiling is one of the main physical processes, which that take place in heat exchange equipment designed for various purposes. The problem of removing large thermal loads from the heated surface is important for nuclear energy, chemical industry, metallurgy, electronics and other areas where intense heat is released. Boiling processes in process equipment perform important protective functions and can control its effectiveness.
According to the boiling curve, with increasing temperature power, the flow passes through five regions, starting from the single-phase region of free convection and ending with the region of developed film boiling.
The purpose of this article is an analytical study of heat transfer at spontaneous transition to the film boiling (explosive type of boiling), taking into account the unsteady nature of this process.
In order to achieve the aim of this research, two analytical approaches were used, namely, the symmetry method and the Laplace method. As a result of mathematical transformations, expressions for the nonstationary temperature distribution and the Nusselt number are obtained. The obtained expressions make it possible to analyze the dynamics of non-stationary heat exchange processes. The results of analytical and numerical modeling were also compared. It was found that the results of the self-similar solution have a better comparison with numerical data compared to the results according to the Laplace method.

This study aims to determine the effect of corn leaf pruning on soybean growth and yield in an intercropping system. This research was carried out on farmers' land in Simpang Village, Berbak District, Tanjung Jabung Timur Regency from July - October 2020. This research was carried out using a Randomized Block Design (RBD) with 5 replications. Pruning treatments based on the position of the leaves on the stem were : without pruning (control/p0), pruning 3 leaves at a position near the soil surface (p1), pruning 3 leaves at a position below the cob (p2), and pruning 3 leaves at a position above the cob (p3). The variables observed included soybean plant height (cm), number of pods per plant, number of filled pods per plant, weight of 100 dry seeds (g), and soybean dry seed yield. The results showed that the highest soybean plant height was obtained without pruning and pruning 3 corn leaves near the soil surface, but produced the lowest number of pods per plant, number of filled pods, and the lowest soybean dry seed yield. The number of pods per plant, the number of containing per plant, and the highest soybean dry seed yield were obtained at pruning of 3 leaves under the cob and 3 leaves of corn above the cob. In corn, the highest yield was obtained by pruning 3 leaves below the cob and 3 leaves above the cob. The diversity of soybean dry seed yields in this study was determined jointly by the diversity of the number of pods per plant, the number of filled pods per plant, and the weight of 100 dry seeds. Partially, only the number of pods contained per plant and the weight of 100 dry seeds significantly played a role in determining the amount of dry soybean yield, while the number of pods per plant had no significant role in determining the diversity of dry seed yields. Land use with corn and soybean intercropping system can increase land productivity so that it is more efficient with LER value > 1 in all positions of corn leaf pruning.
