摘要

本研究建议在计算流体动力学(CFD)模型中将流体蛋制品作为相变材料(PCM)建模,从而模拟鸡蛋的烹饪过程。研究人员制作了一个简化的物理原型,用于进行实验以调整数学模型的简化版本。随后,利用这些信息建立了一个真实鸡蛋的完整数学模型,并与实验数据进行了比较。确定了相变温度范围和初始化相变所需的能量。对两个模型的传热系数进行了估算。热加工和相变实验在 90 至 100 ℃ 的温度下进行。真鸡蛋模型与其他地方报告的实验数据进行了验证。模拟评估了煮鸡蛋所需的时间(800-1200 秒),显示了温度的均匀上升和相变。不过,也观察到模拟中可能存在高估的情况,这可能是由于量化技术的差异和烹饪过程不均匀造成的。

Modeling of cooking and phase change of egg white using computational fluid dynamics

Modeling of cooking and phase change of egg white using computational fluid dynamics
This study proposes simulating the cooking of eggs by modeling fluid egg products as phase-change materials (PCMs) within a computational fluid dynamics (CFD) model. A simplified physical prototype was built to conduct experiments to tune a simpler version of the mathematical model. The information was later used to build a complete mathematical model of a real egg that was compared with experimental data. Phase transition temperature ranges, and the energy required to initialize the transition were specified. Heat transfer coefficients were estimated for both models. Experiments for thermal processing and phase change were conducted at temperatures between 90 and 100 °C. The real egg model was validated with experimental data reported elsewhere. The simulations assess the time required to cook an egg (800–1200 s), demonstrating a homogeneous increase in temperature and phase transition. However, potential overestimation in simulations was observed, likely due to differences in quantifying techniques and non-uniform cooking processes.
