Proper climatic conditions in greenhouses are one of the major parameters to ensure optimum crop development. The installation heating and cooling systems common solution form a proper microclimate inside greenhouse. However, operation these is accompanied by energy consumption. Therefore, many methods alternative sought encounter this issue. A system which has been examined as an for full or p...

This study is focused on the and development of a gas-to-liquid heat pipe exchanger (HPHE) based numerical experimental analysis. Stainless steel pipes were installed inside in form three equilateral triangles, staggered into hexagonal configuration to simulate waste recovery from hot exhaust gas water flow. The first main aim this was 3D design analysis, which used create calculate effect simi...

In this work, numerical and experimental analyses of a double-pipe heat exchanger with SiO2 nanoparticles were performed. The study was conducted by using the k-e turbulence model Galerkin weighted residual finite element method. nanofluid used in inner pipe at various solid particle volume fractions. Effects flow rate temperature on overall transfer coefficient examined. Brownian motion effect...

This work compares a theoretical model with consolidated numerical related to the thermodynamic performance of boehmite alumina nanoparticles in different formats counterflow double pipe heat exchanger. The shapes non-spherical under analysis are platelets, blades, cylindrical, and bricks. second law thermodynamics is applied determine Nusselt number, pressure drop, thermal efficiency, viscous ...
