This article presents a numerical investigation of the heat exchanger design effect on the performance of closed cycle, two-bed adsorption cooling systems with silica gel as adsorbent and water as refrigerant. It is well known that the shorter the cycle time, lower is the performance (cooling cap...
Partly due to their simplicity, these rules do not assure a safe heat-exchanger design in all cases. This is the main reason why new tubesheet design rules were developed in 1981 in France for the French pressure vessel code CODAP. For fixed tubesheet heat exchangers, the new rules account...
Heat exchangers play a key role in wide industrial applications. Due to their complex design and high manufacturing cost, their efficient operation and optimum design are quite important for overall c关键词: Cohort intelligence algorithm Cost optimization Economic optimization Shell-and-tube heat exchange...
A Small Tube and Shell Heat Exchanger with parallel/counter flow that would serve as an auxiliary cooling system for the radiator was designed and developed. Keywords― Flow, Fluid, Heat, Transfer and Tube. Significance― The work would enhance local production and reduce down-time caused by ...

The Ground Heat Exchanger Design Tool (DT) is a Python package that can quantify the short- and long-term thermal interaction in a ground heat exchanger (GHE). The long-term thermal response g-functions are computed live-time with pygfunction. The DT contains a fast monthly hybrid time step...
In the present study, three-dimensional numerical simulations of turbulent flow in shell-and-tube heat exchangers (STHEs) are performed, in which a novel design of successive expansion and contraction of tubes (SECTs) is used. In these STHEs, two types of the SECT are used: (1) the SECT...
This paper seeks to introduce a heat pipe heat exchanger (HPHEX) as an alternative design of the intercooler. The proposed HPHEX design takes advantage of the convenience of the geometry of miniature heat pipes to provide a reduction in pressure losses and weight when compared to conventional ...
An advanced heat exchanger design is key for both the economic and performance viability of STPPs coupled to supercritical power cycles. The most promising proposals include compact heat exchangers (CHX) and, particularly, printed circuit heat exchangers (PCHE). PCHE consists of chemically etched plat...
A Printed Circuit Heat Exchanger (PCHE) is one of the most promising heat exchangers of an intermediate heat exchanger (IHX) in High Temperature Gas-cooled Reactors (HTGRs), since PCHEs offer high effectiveness and a compact size. A PCHE consists of many micro-wavy channels, which increase ...
