Semi-spherical fins are widely considered to be one of the best thermal exchangers
available. It is widely employed, including aero planes, chemicals and electronic kits and …

In this study, an exact analytical solution for the convective heat transfer equation from a
semi-spherical fin was presented. To obtain a mathematical model, the system was …

We find an optimal design of a structure described by a Sturm-Liouville (SL) problem with a
spectral parameter in the boundary conditions. Using an approach from calculus of …

Due to the use of welded finned tubes in heat exchangers, gas blocks are characterized by
very good electric energy production performance, and their reliability can reach 98 …

We study a Sturm–Liouville problem in the cross-section of the ocean waveguide covered by
pack ice. We prove the basis properties of the eigenfunctions, the convergence of the …

The stiffness maximization of elastic straight Euler-Bernoulli beams under the action of
linearly distributed loads is addressed. The goal is achieved by minimizing the average …

When in the differential equation describing the behaviour of a dynamical system the time
derivative of the input is involved, a naive realization may mislead the application of the …

Heat exchangers are present in our daily living and industrial applications. The size scale of
heat exchangers is very large ranging from very small chips in electronics to huge …

A fin serves as an extended surface to enhance the heat transfer from a larger heated mass
to which it is attached. The authors consider a fin in the steady‐state at high temperatures …

A fin serves as an extended surface to enhance the heat transfer from a larger heated mass
to which it is attached. We use a multiobjective optimization (MO) approach for a fin in steady …
