Flow And Heat Transfer

В работе рассмотрены устойчивые стационарные решения задачи гидродинамики и теплообмена в плоском канале с обратным уступом для экстремально больших чисел Рейнольдса и параметра расширения потока $ER$. Задача решена путем численного интегрирования двумерных уравнений Навье--Стокса в переменных «скорость--давление» и уравнения баланса тепла в диапазоне чисел Рейнольдса $500 \leqslant \mathrm{ Re }\leqslant 3000$ и параметра расширения потока $1.43 \leqslant ER \leqslant 10$ для числа Прандтля $\mathrm{Pr} = 0.71$. Достоверность полученных результатов подтверждена их сравнением с литературными данными. Представлены подробные картины течения и перегрева потока, а также профили продольной компоненты скорости и перегрева в поперечном сечении канала. Проанализировано поведение коэффициентов трения, сопротивления и теплоотдачи (числа Нуссельта) по длине канала в зависимости от параметров задачи.

Paint Drying

In the automotive manufacturing process, the paint drying process is very important to improve the appearance of the vehicle. In the present study, the fluid flow and heat transfer around a vehicle were numerically investigated for the purpose of predicting the drying performance of the paint drying process. In order to simulate the operating conditions of the paint drying process, the following techniques were used: relative moving boundary conditions, multiple reference frames, and conjugated heat transfer. The present numerical method was verified by comparing the numerical results of the temperature at several monitoring points on a vehicle, while using the experimental data. To evaluate the drying performance quantitatively, the absorbed heat energy that is closely related to the drying of paint was obtained from the numerical simulation. It was found that the drying performance is greatly affected by operating conditions such as the temperature and flow rate of blowing air. To improve the drying performance, the operating conditions of the paint drying process were optimized using the numerical results of various operating conditions.

Uncertainty analysis in the initial stages of any experimental work is essential in obtaining high-quality data. It insures that the proposed experiment has been thoroughly planned, and that the quantities to be calculated from the experimental measurements will be known with reasonable accuracy and precision. While an uncertainty analysis helps insure reliable results, there is another equally significant aspect in the experimental planning stage: minimization of experimental equipment expenses. A method is presented here in which these two essential experimental elements are combined and viewed as an optimization problem for systematic examination. The analysis allows a systematic search for the least expensive combination of experimental equipment that will give the desired accuracy of results. For the numerical solution the Sequential Gradient Restoration Algorithm (SGRA) is selected. A typical experimental fluid flow and heat transfer problem is given, demonstrating the analysis and numerical solution.
