📝عنوان: بررسی مدل های موجود در پنجره ی مبدل های حرارتی(Heat Exchanger Models)
💬توضیحات:
1️⃣ Macro Models (ungrouped and grouped)
• ANSYS FLUENT allows you to chose between two heat transfer models
• Simple effectiveness: The coolant can be single phase or two-phase
• Number of Transfer Units (NTU)
• A 1D flow is assumed for the auxiliary or coolant flow
2️⃣ Dual-Cell-Based Heat Exchanger Models
• Uses the NTU method for heat transfer calculation
• Two volume zones defined on top of one another
• Primary flow
• Auxiliary flow
• Allows more flexibility as far as the shape of the heat exchanger is concerned
