Present study uniquely explores the thermal and hydraulic performance of three different heat sink designs: plate-fin, porous metal foam, and hybrid of finned metal foam, using both experimental and numerical methods under the same impingement cooling conditions. The innovation of this study is its thorough evaluation of these designs using the Local Thermal Non-Equilibrium (LTNE) method to precisely simulate heat transfer within porous materials. Key metrics such as Nusselt number, and pressure drop were assessed. The findings reveal that both porous and hybrid heat sinks surpass the traditional plate-fin design, with the hybrid model showing the highest thermal efficiency due to its larger effective surface area and improved flow disruption. Experimental results indicate that utilizing a hybrid heat sink and metal foam at an input power of 30 W increases the average Nusselt number by 35.82 % and 24.79 %, respectively, compared to the plate-fin heat sink, which, according to the numerical results, these values are 34.76 % and 20.65 %, respectively. These results provide valuable insights for designing advanced thermal management systems for compact electronic devices. The Figure of Merit (FOM) is determined by simultaneously considering both thermal and hydraulic performance. the average FOM for the hybrid and metal foam heat sinks increases by 32.62 % and 19.47 %, respectively, relative to the plate-fin configuration. An increase in the Nusselt number and enhancement of the FOM in heat sinks lead to improved heat transfer efficiency and better protection of electronic components against thermal stress.

It is the first investigation to date which considers a chemically reacting nanofluid in a partitioned cavity. Defining suitable variable transformations, the governing equations are reduced to a set of nondimensional equations which are solved numerically using the finite difference method. An increase in Darcy number leads to a decrease in fluid flow of nanofluid layer and an increase in flow velocity of porous layer and maximum temperature. For higher Rayleigh number, the flow intensity and remaining oxidizer concentration increase; however, the maximum temperature diminishes. Moreover, the magnitude of the stream function and maximum temperature increase, while the remaining amount of oxidizer decreases with increasing Frank-Kamenetskii number and Hartmann number. However, the opposite effect is recognized for the increase in the porous layer thickness. As the volume fraction of nanoparticles increases, the maximum temperature first increases and then decreases, while the converse scenario is observed for the magnitude of flow circulation in the fluid layer.</div></div>","PeriodicalId":23062,"journal":{"name":"Thermal Science and Engineering Progress","volume":"67 ","pages":"Article 104147"},"PeriodicalIF":5.4,"publicationDate":"2025-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145227260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This modified still was also integrated with copper chips to enhance thermal characteristics inside the still. Additionally, the modified stills were also tested under the influence of external condensation using cool water.

Supercritical helical heat exchangers operating under pulsating flow has not been explored which forms the central theme of this study. Flow through helical channels with supercritical fluids is characterized by intricate secondary flow phenomena, driven by the steep gradients in thermophysical properties and the interaction between Dean vortices and Lyne vortices, particularly under oscillating flow conditions. The simulations are conducted for typical operating conditions having a peak mass flow rate of 0.00894 kg/s, at 8 MPa. Multiple pulsating flow profiles such as square, cosine, and triangular waveforms at frequencies of 2, 4, and 8 Hz are applied to both circular and square cross-sectional geometries, with and without internal twists. A key finding is the emergence of Lyne vortices, which rotate in the opposite direction to Dean vortices during the deceleration phase of pulsating flow. This phenomenon is attributed to annular velocity distributions and contributes to enhanced radial mixing. Notably, a 4 Hz square-wave pulsating flow in a circular channel resulted in improved heat transfer compared to steady flow, albeit with a significant pressure drop. Among all scenarios, the 4 Hz cosine waveform in a circular channel achieved the highest heat transfer enhancement (<em>Nu</em> = 126.79) with minimal pressure drop.
