A heating combining forced convection and short‐infrared radiation was investigated. one‐dimensional model taking into account shrinkage product developed to get temperature moisture content evolutions during drying. The water diffusion coefficient estimated by inverse method. sensitivity analysis numerical tests showed relevance using objective function both mass measurements for...
The control of the melting temperature in polymer forming process is essential to ensure quality final products. current article reports a study conducted develop an experimental device equipped with one intrusive thermal instrument. sensor placed within flow allows for measurement profiles. At same time, modeling cell (TMC) determine its capability characterize and rheological behavior flow. A sensitivity analysis performed quantify uncertainty because presence instrumentation. mounted on...
Abstract Polymer processing requires reliable monitoring equipment to ensure product quality, improve energy efficiency and apply advanced control strategies. This work tests an instrumented annular duct as a nozzle on the downstream side of screw‐barrel analyze thermal behavior polymer flow in injection molding machine. The plasticization step is first studied, then virtual cycles are performed. measurements via show that melt temperature decreases during fast production, due lack residence...
During the recycling of polypropylene (PP), some pollutants are likely to be present in polymer. Most these polyethylene (PE) which tends form a heterogeneous blend with PP due their incompatible nature. In study, and PE were extruded different volume fractions PE. The pressure drop temperature variation within flow cylindrical die studied. A finite element model was used order predict rheological behaviors studied polymer mixture ratios. results obtained this work show that response is very...
Abstract This paper deals with the drying behavior of poly(vinyl alcohol) aqueous solution containing an active substance and placed into a Petri box. The objective is to reduce time while respecting some constraints. To succeed, it important understand complex mechanisms governing heat mass transfers. During drying, product thickness shrinks its properties evolve. Drying kinetics in convective infrared radiation are presented.
This study comprehensively investigates impinging jet cooling mechanisms within a thermal regulation framework. Utilizing an innovative approach based on the Smart Element of Cooling with jets and transverse airflow, 3D numerical model Inverse Heat ConductionProblem (IHCP) is developed.This quantifies heat exchange distribution at wall confined cylindrical space margin error below 3%.The demonstrates effectiveness algorithm in maintaining target rates, highlighting significant influences...
Abstract This study deepens the understanding of heterogeneity thermal exchanges in a cylindrical channel cooled by impinging water jets, considering influence transverse air flow and gravity. The results reveal distinct cooling zones, with higher intensity near stagnation points, where Critical Heat Flux (CHF) recorded 4.29 MW/m2 corresponds to heat transfer coefficient 19.46 KW/(m2 · K). CHF value decreases 50% jet overlap points ranges between 39% 43% upper lower zones channel, perfectly...
Modeling and optimization of LSR parts require an accurate kinetic modeling the material crosslinking. Calorimetric mechanical measurements for different temperature ramps are used in order to calculate crosslinking extent as a function time temperature. These numerically treated determine parameters representative model. The chosen model will be simulate molded design controlled molding setup.

To overcome the inlet temperature uncertainties during an in-line thermo-rheological characterization and to further apply a differential convection method for injection molding process, concept of device designing is proposed in this work. An analytical numerical investigation proves that can provide information on viscosity material via thermal measurements, despite poorly known temperature.
