The heat loss caused by radiation and persistently laminar natural convection in a solar cooker cavity that has rectangular or trapezoidal are computationally explored this paper. hot bottom the adiabatic side wall both taken into account. Two possibilities considered for top wall: first, cold wall, and, second, losses from wind-induced radiation. parameters of various depth cavities have been ...

The generalization of p-frame in Banach spaces is considered in this paper. The concepts of an $tilde{X}$-frame and a system conjugate to $tilde{X}$-frame were introduced. Analogues of the results on the existence of conjugate system were obtained. The stability of $tilde{X}$-frame having a conjugate system is studied.

We present a GPU-accelerated method for large scale, coupled incompressible fluid flow and heat transfer problems. A high-order, nodal discontinuous Galerkin is utilized to discretize governing equations on unstructured triangular meshes. semi-implicit scheme with explicit treatment of the advective terms implicit split Stokes operators are used time discretization. The pressure system solved c...

This paper presents a computational model for predicting the location at which the glass fiber solidifies during a highspeed drawing process. Although modeling of the optic fiber drawing process has been of interest for the past two decades, traditional fiber drawing process uses small diameter preforms and low draw speeds, where the glass usually solidifies and turns into fiber inside the furn...

Micro-convection is a strategic area in transport phenomena, since it is the basis for a wide range of miniaturised high-performance applications. Microchannel heat-sinks are appealing solutions to the increasing heat dissipation demands, especially in electronic devices. Literature reveals that in the single-phase continuum regime, the behaviour of micro-convection significantly differs from t...

A novel immersed boundary (IB) method has been developed for simulating multi-material heat transfer problem – a cylinder in a channel heated from below with mixed convection. The method is based on a second-order velocity/scalar reconstruction near the IB. A novel algorithm has been developed for the IB method to handle conjugate heat transfer. The fluid–solid interface is constructed as a col...
