در تحقیق حاضر در مورد اثرات ارتفاع دندانه در میکروکانال دندانه‌دار دو بعدی، بر روی پارامترهای انتقال حرارت و دینامیک سیالات محاسباتی جریان آرام نانوسیال آب-اکسید آلومینیم است. بررسی‌های این تحقیق به صورت عددی با نرم افزار تجاری فلوئنت3/6 برای اعداد رینولدز10 و 100، برای چهار حالت مختلف ارتفاع دندانه انجام شده است. افزایش ارتفاع دندانه‌های داخلی یا مغشوشگرهای جریان، عملکرد انتقال حرارت جابجایی د...

The paper presents the results of experimental research on pool boiling heat transfer dielectric liquid FC-72. Measurements were made at atmospheric pressure open surfaces with microchannels. Heat surfaces, in form parallel milled microchannels, copper. rectangular cross-sectional microchannels 0.2 to 0.5 mm deep and 0.4 wide. compared a smooth flat surface, provided five-fold increase coeffici...

The proper addition of additives to pure CO2 can improve the performance as a working fluid. By fluid, we mean fluid used for CO2-based transcritical power cycle characterized by R134a CO2. Hence, an experimental investigation pressure drop characteristics supercritical CO2/R134a mixture in rectangular microchannel was conducted. For this purpose, accurate and stable thermal-hydraulic system de...

We report the design of a multipass microrheometer that can be fully customizable at low cost and reasonable time, which allows us to perform experiments rapidly in broad range shear rates (i.e., from 0.1 100 s−1), using small amounts material just some milligrams). Additionally, low-cost approach opens for an easy parallelization setup makes it suitable high-throughput rheological experimentat...

Cells docking inside microfluidic devices is effective in studying cell biology, cell-based biosensing, as well drug screening. Furthermore, single and regularly cells the microstructure of systems are advantageous different analyses exposed to equal concentration mechanical stimulus. In this study, we investigated bottom wall microgrooves with semicircular rectangular geometries sizes which su...

Distinctive recent research and experimental trends in microchannels for heat transfer thermal management applications are investigated via a novel framework. The qualitative literature analysis was performed from four perspectives: materials, enhanced flow control, design, sustainability (MEDS). findings revealed that microchannel (MC) performance (HTP) could be achieved by adding asymmetrical...
