“…Therefore, forest scientists have to use packages from unfamiliar fields of study. Then, how to integrate a third-party software package [10][11][12] with virtual forests/trees would be the next big challenge. The second drawback is the current computational power of desktop computers, which limits the simulation of physical processes in forests [13,14].…”

Our previous studies discussed the potential of measuring virtual trees using computational virtual measurement (CVM). CVM is a general methodology that employs observational techniques in lieu of mathematical processing. The advantage of CVM lies in its ability to circumvent mathematical assumptions of tree shapes at the algorithmic level. However, due to the current computational limitations of desktop computers, the previously developed CVM application, namely, virtual water displacement (VWD), could only act as a primary theoretical testimonial using an idealized point cloud of a tree. The key problem was that simulating a massive number of virtual water molecules (VMMs) consumed most of the computational resources. As a consequence, an unexpected empirical formula for volume calibration had to be applied to the output measurement results. Aiming to create a more realistic simulation of what occurs when water displacement is used to measure tree volume in the real world, in this study, we developed a new physical scenario for VWMs. This new scenario, namely, a flood area mechanism (FAM), employed footprints of VWMs instead of quantifying VWM counts. Under a FAM, the number of VMMs was reduced to a few from several thousands, making the empirical mathematical process (of the previously developed physical scenario of VWMs) unnecessary. For the same ideal point clouds as those used in our previous studies, the average volume overestimations were found to be 6.29% and 2.26% for three regular objects and two artificial stems, respectively. Consequently, we contend that FAM represents a closer approximation to actual water displacement methods for measuring tree volume in nature. Therefore, we anticipate that the VWD method will eventually utilize the complete tree point cloud with future advancements in computing power. It is necessary to develop methods such as VWD and more CVM applications for future applications starting now.

“…The Kutta−Merson method with automatic step selection and proprietary software (COND-KINET-1 [13]) were used to solve the system of ordinary differential equations (1)−( 4), (6). The TOL parameter, which governs the choice of smaller steps, was set to a level at which the obtained results ceased to change with further reduction of the TOL value.…”

Numerical modeling of the cooling of a vapor-gas mixture by evaporating water drops has been carried out. An expression is proposed using the characteristic temperature, which determines the dependence of the cooling time on the initial temperature of the mixture. A technique for determining the characteristic temperature based on the results of numerical simulation is presented. An estimate of the error in the results of using the obtained expressions is made. Keywords: vapor-gas mixture, thermal relaxation, numerical simulation, heating and evaporation of droplets, vapor-gas mixture cooling time, characteristic temperature.
