Abstract Given a manifold M $$ \mathbbm{M} $$ admitting a maximally supersymmetric consistent truncation, we show how to formulate new consistent truncations by restricting to a set of Kaluza-Klein modes on M $$ \mathbbm{M} $$ invariant under some su

This work presents a theoretical study of fouling in flat plate solar collectors. The thermal performance of solar collectors is determined by operating variables such as surface area, network configuration, and flow distribution, as well as external

This work introduces a heat exchanger design approach for units using combined twisted tape and twisted tube heat transfer enhancement technology. In design and retrofit, the use of these systems is characterized by heat transfer enhancement on both

The geometrical features of twisted tube exchangers enhance the thermo-hydraulic performance for the same fluid velocity compared to conventional heat exchangers. The benefit of its use becomes evident in design as the required heat duty is transferr

The thermohydraulic performance of the surfaces used in plate heat exchangers are directly related to the surface geometrical features which have an impact on the size of a heat exchanger. In the case of chevron corrugations, the variables are the ch

As a result of the wide use of tubular heat exchangers in industry and considering the main heat transfer and friction limitations they possess compared to new technologies, heat transfer promoters of different shapes have appeared in recent years to

From the thermal point of view, the main operational problems conventional heat exchangers of the tubular type face are the prevalence of the laminar sublayer on the surface immediately adjacent to the heat transfer surface that is responsible for lo

This paper shows the development of a design approach for plate and fin heat exchangers to meet fixed dimensions. This approach adopts the concept of volume design region that establishes the limits within which the physical dimensions (length, width
