“…They showed that a double pass arrangement cools the channel walls down more symmetrically, in comparison to the simple pass arrangement, with better uniformity in wall temperature distribution. The uniformity index increases by 16.7% compared to the original heat exchanger. However, power consumption for handling the coolant fl ow increases in comparison to the original solution.…”

“…The need of investigation of the effect of corrugated fl at plate heat exchanger with and without baffl es on the thermal-hydraulic characteristics, including effi ciency of heat transfer and fl ow resistance in heat exchanger, was recognized by Rios-Iribe et al 16 . The impact of plates number and distance between plates on the heat transfer and the friction factor were studied over a wide Reynolds number range in the case of non-Newtonian fl uids fl owing through the plate heat exchangers.…”

The paper presents a Computational Fluid Dynamics (CFD) numerical study for a new design of a plate heat exchanger with two different fl ow patterns. The impact of geometric characteristics of the two studied geometries of exchanger plates on the intensifi cation process of heat transfer was considered. The velocity, temperature and pressure distributions along the heat exchanger were examined. The CFD results were validated against experimental data and a good agreement was achieved. The results revealed that geometrical arrangement of the plates strongly infl uence the fl uid fl ow. An increase in the Reynolds number led to lowering the friction factor value and increasing the pressure drop. The confi guration II of the plate heat exchanger resulted in lower outlet hot fl uid temperature in comparison with the confi guration I, which means improvement of heat transfer.

“…Computational fluid dynamics (CFD) is a branch of fluid mechanics that makes use of different algorithms and numerical analysis in order to analyze and solve problems involving fluid flows. A number of studies have been performed using CFD to understand the internal flow (Bahirat & Joshi, ; Bouvier et al, ; Forooghi, Flory, Bertsche, Wetzel, & Frohnapfel, ; Khoshvaght‐Aliabadi, Zangouei, & Hormozi, ; Ray, Das, & Vajjha, ; Yang & Liu, ), the design (Arie, Shooshtari, Dessiatoun, Al‐Hajri, & Ohadi, ; Giurgiu, Pleşa, & Socaciu, ; Liu, Bu, & Xu, ; Wang et al, ; Wang, Deng, Zhao, Zhu, & Che, ; Zhang, Wang, Han, Zhu, & Peng, ), and the heat transfer (Asif, Aftab, Syed, Ali, & Muizz, ; Bhattad, Sarkar, & Ghosh, ; De Mello, Villanueva, Scuotto, Donato, & Ortega, ; Rios‐Iribe, Cervantes‐Gaxiola, Rubio‐Castro, & Hernández‐Calderón, ; Sunden, ; Tiwari, Ghosh, Sarkar, Dahiya, & Parekh, ) of PHEs, but these works did not present any analysis of how product texture evolves. The aim of this study is to determine texture loss in a PHE using rheological measurements and a CFD model to evaluate the mechanical stress inside a PHE.…”

The producers of dairy products must control the final quality of products by evaluating their textures. Certain devices on production lines such as heat exchangers cause texture losses, affecting product consistency. The mechanical stress due to plate heat exchangers is often at the origin of this change, although evaluations of products as they flow through heat exchangers are lacking. This work proposes a coupled approach to determine texture loss for yoghurt in a heat exchanger using rheological measurements and a Computational Fluid Dynamics approach. The results are based on the quantification of mechanical stress and compared with experimental measurements performed to evaluate texture loss in yoghurt samples. Practical applications The objective of this work is to optimize the production lines for dairy products such as yoghurts. To date, texture losses appear during their manufacture, resulting in a decrease in viscosity compared with the desired quality on the final product. By describing the behavior of yoghurt in a plate heat exchanger, the Computational Fluid Dynamics can diagnose mechanical stress and provide information that producers cannot access to improve their process. The work was carried out on a laboratory plate heat exchanger, which was used to select the yoghurt cultures used to produce the finished product. Simulations bring mechanical stress information to producers. They can thus correlate it to the loss of texture. The aim is to be able to reproduce this mechanical stress with devices other than the plate heat exchanger, but by first evaluating by modeling the mechanical stress to be applied.

“…Rios Iribe et al [7] investigated, using CFD and hexahedral meshes, momentum and heat transfer of a nonNewtonian fluid in steady laminar regime through a plate heat exchanger at constant wall temperature. Although the flow pattern was highly complex, under an adequate definition of the characteristics parameters, it was possible to establish simple correlations between the dimensionless numbers that characterize the thermalhydraulic behavior of plate heat exchangers.…”

Abstract. The article deals with optimization of undulated heat transfer surface of plate heat exchanger. The goal of optimization is not only to increase effectiveness of heat transfer but also to reduce the pressure drop. Using four optimization parameters, the function describing the shape of corrugations is defined and these parameters are optimized. A simple steepest descent gradient method and stochastic Monte Carlo method are used, the optimum shape of the heat exchange surface is searched for four values of the pressure drop. It was found that a simple steepest descent method quickly gets stuck in a local extreme and the resulting configurations were found only by changing the slope of the waves. The stochastic method enables full optimization through the optimization space and find completely different waveforms with similar values of target function. The question, which shape of the waves on the heat transfer surface is the best, is still open.
