THERMAL and HYDRAULIC PERFORMANCE ANALYSIS of a SHELL and TUBE HEAT EXCHANGER UNDER VARYING FLOW VELOCITIES USING CFD

Year 2025, Volume: 1 Issue: 2, 8 - 15, 29.09.2025

Abstract

This study investigates how flow velocities between 0.1 and 1.0 m/s affect the thermal and hydraulic performance of a tube-in-tube heat exchanger under constant inlet conditions (cold stream at 298 K and hot stream at 373 K). As the flow rate increases, convective heat transfer intensifies, yielding a pronounced rise in the hot stream’s Nusselt number, while the cold stream experiences a slight reduction due to shorter residence times. Experimentally obtained Prandtl Nusselt correlations align closely with well-established empirical models. Simultaneously, the pressure drops across the exchanger increases with velocity following an approximately quadratic relationship, with critical Reynolds numbers clearly marking the transition between flow regimes. Numerical results are presented alongside analytical visuals to enable both visual and quantitative interpretation of the exchanger’s behavior. These findings provide practical guidance for optimizing design and operating parameters in real-world applications, and future research could investigate different materials and geometric configurations to further enhance performance.

CFD KULLANARAK DEĞİŞEN AKIŞ HIZLARI ALTINDA BİR KABUK VE BORU ISI DEĞİŞTİRİCİSİNİN TERMAL ve HİDROLİK PERFORMANS ANALİZİ

Year 2025, Volume: 1 Issue: 2, 8 - 15, 29.09.2025

Abstract

Bu çalışma, 0,1 ile 1,0 m/s arasındaki akış hızlarının sabit giriş koşulları altında (298 K'de soğuk akış ve 373 K'de sıcak akış) bir tüp içinde tüp ısı değiştiricisinin termal ve hidrolik performansını nasıl etkilediğini araştırmaktadır. Akış hızı arttıkça, konvektif ısı transferi yoğunlaşır ve sıcak akışın Nusselt sayısında belirgin bir artışa neden olurken, soğuk akış daha kısa kalma süreleri nedeniyle hafif bir azalma yaşar. Deneysel olarak elde edilen Prandtl Nusselt korelasyonları, iyi kurulmuş ampirik modellerle yakından uyumludur. Eş zamanlı olarak, değiştirici boyunca basınç düşüşleri, yaklaşık olarak ikinci dereceden bir ilişkiyi takip ederek hızla artar ve kritik Reynolds sayıları akış rejimleri arasındaki geçişi açıkça işaretler. Eşanjörün davranışının hem görsel hem de nicel yorumlanmasını sağlamak için sayısal sonuçlar analitik görsellerle birlikte sunulmuştur. Bu bulgular, gerçek dünya uygulamalarında tasarım ve işletme parametrelerini optimize etmek için pratik rehberlik sağlar ve gelecekteki araştırmalar, performansı daha da artırmak için farklı malzemeleri ve geometrik yapılandırmaları inceleyebilir.
