The objective of this paper is to develop and test a model of cost estimating for the shell and tube heat exchangers in the early design phase via the application of artificial neural networks (ANN). An ANN model can help the designers to make decisions at the early phases of the design process. With an ANN model, it is possible to obtain a fairly accurate prediction, even when enough and adequ...

The conventional virus isolation technique was compared with a 24-h shell vial centrifugation culture technique and with a 48-h tube culture method for the detection of cytomegalovirus (CMV) in MRC-5 cells. Of 200 clinical specimens tested, 41 were positive for CMV by at least one procedure. Indirect immunoperoxidase staining was positive for 32 (78.0%) of 41 specimens in the tube culture metho...

Modeling the dynamics of shell-and-tube heat-exchangers is an important step in developing dynamic system models of liquid chillers that are used for studying transient system performance. Existing literature on the subject is limited and much of what exists uses either a lumped parameter approach or a finite volume approach for the shell-and-tube heat-exchangers. The lumped parameter approach ...

A conical shell-tube design with non-uniform fins was addressed for phase change latent heat thermal energy storage (LHTES). The shell filled nano-enhanced material (NePCM). cone aspect ratio of the and were adopted as geometrical parameters. type volume fraction nanoparticles other investigated alumina, graphite oxide, silver, copper. finite element method employed to solve natural convection ...

The distribution of soil particles and planting tube space position affects reversal cultivated land and fertilization seeder seeding performance. Through the establishment of ratary tiller system coordinate system; Firstly giving the analysis of soil grain not heel cover shell collision and the first meeting with cover shell collisions motion situation, through Matlab found the first meeting w...

Elastocaloric cooling is considered an environmentally friendly future alternative to vapor-compression technology. Recently, a shell-and-tube-like elastocaloric regenerator loaded in compression has demonstrated record-breaking heat-pumping performance and fatigue-resistant operation. The aim of this work thus present new 1D numerical model simulate optimize the operation with design. In first...

Shell-and-tube heat exchangers are widely used in many research fields and industrial production processes, but little has been conducted on the use of for drying crops. This study a numerical simulation temperature, velocity, pressure based shell-and-tube fluids exchanger biomass particle hot-blast stove. The correctness results was verified by test data before simulation, mesh to be irrelevan...
