Проверка адекватности математической модели программного комплекса Locairheat для расчетов систем обеспечения теплового режима помещений воздушно-отопительными агрегатами

Abstract

Приводятся перечень основных уравнений, включенных в математическую модель, тип алгебраической модели турбулентности. Описываются проведенные для определения коэффициента турбулентности лабораторные и вычислительные эксперименты. Результаты экспериментов представлены в виде графика (рис. 2). Выбирается коэффициент, соответствующий результатам лабораторных экспериментов. Описываются натурный и вычислительный эксперименты, выполненные для оценки адекватности предложенной математической модели в программном комплексе Locairheat. В натурном эксперименте исследуются параметры приточной нагретой воздушной струи от газового воздушно-отопительного агрегата марки Monzun фирмы Mandik с возможностью полной, частичной рециркуляции и прямотока. Вычислительный эксперимент моделируется по исходным параметрам натурного эксперимента. Приводятся их результаты, проводится оценка полученных результатов на основе статистического критерия Фишера. Делается вывод об адекватности принятой математической модели.

Provides a list of the basic equations that are included in the mathematical model, the type of algebraic turbulence model. Describes conducted to determine the coefficient of turbulence laboratory and numerical experiments. The experimental results are plotted (Figure 2). Coefficient is selected corresponding to the results of laboratory experiments. Describes the full-scale and computational experiments performed to assess the adequacy of the proposed mathematical model in the software package «Locairheat». In the field experiment investigated parameters plenum heated air stream from the gas air-heating unit of the brand «Monzun» company «Mandik» with the possibility of full or partial recycling and forward flow. Computational experiment is modeled on the original parameters of natural experiment. Present the results, an evaluation of the results of the statistical Fisher´s exact test. The conclusion about the adequacy of the mathematical model.
