Transient temperature distribution in finite multi-composite cylinders.

Numerical Prediction of Temperature Distribution in Transient RTM Process

Resin Transfer Molding (RTM) is a composite manufacturing process. A preformed fiber is placed in a closed mold and a viscous resin is injected into the mold. In this paper, a model is developed to predict the flow pattern, extent of reaction and temperature change during filling and curing in a thin rectangular mold. A numerical simulation is presented to predict the free surface and...

The Effect of Fiber Breakage on Transient Stress Distribution in a Single-Lap Joint Composite Material

In the present study, the transient stress distribution caused by a break in the fibers of an adhesive bonding is investigated. Transient stress is a dynamic response of the system to any discontinuity in the fibers from detachment time till their equilibrium state (or steady state). To derive the governing dynamic equilibrium equations shear lag model is used. Here, it is assumed that the tens...

Three Dimensional Transient Numerical Modeling of Temperature Distribution and Output Power in Photovoltaic Module

According to the effect of temperature on the output power of a photovoltaic module, this research tries to calculate the temperature distribution in a photovoltaic module by numerical solving of the energy balance equations. Therefore, its output power can be accurately predicted. For this purpose, several photovoltaic modules are modeled in detail in the COMSOL software. A new method for calc...
