Non-symmetric heat flux distributions in terms of gravity in solar collector tubes influence buoyancy-driven secondary flow which has an impact on the associated heat transfer and pressure drop performance. In this study ...

A new central receiver concept is being developed that attempts to trap solar rays and limit the re-radiation view factor. It has an array of hexagonal pyramid-like structures that form the absorbing surface facing the ...

In this study, a novel plate methanol reactor (shell and plate) with a higher heat transfer rate compared to the conventional counterparts (shell and tube) was investigated. In fact, in the new configuration, all of the ...

Although the effect of surface roughness on internal forced convection is considered a mature field, very limited work has been done focussing on the effect of surface roughness in the laminar and transitional flow regimes, ...

The application of nanofluids for enhancing the heat transfer rate is widely used in various heat exchanger applications. The selection of oil as the base to prepare nanofluids significantly enhances the thermal performance, ...

On account of nanofluids influence on heat exchangers (HEs), a vigorous discussion can be made to concurrently contrast HEs to one another under the same conditions to detect maximum efficacy. Based on an extensive ...

In this study, the convection heat transfer and pressure drop of titanium dioxide–water nanofluids were modeled by applying the fuzzy C-means adaptive neuro-fuzzy inference system approach for a completely developed turbulent ...

The operating conditions of many heat exchangers are in, or close to, the transitional flow regime. However, in this regime, not a lot of design information is available and some design books even recommend to not design ...
