A screening method for the optimal selection of plate heat exchanger configurations

Abstract

-An optimization method for determining the best configuration(s) of gasketed plate heat exchangers is presented. The objective is to select the configuration(s) with the minimum heat transfer area that still satisfies constraints on the number of channels, the pressure drop of both fluids, the channel flow velocities and the exchanger thermal effectiveness. The configuration of the exchanger is defined by six parameters, which are as follows: the number of channels, the numbers of passes on each side, the fluid locations, the feed positions and the type of flow in the channels. The resulting configuration optimization problem is formulated as the minimization of the exchanger heat transfer area and a screening procedure is proposed for its solution. In this procedure, subsets of constraints are successively applied to eliminate infeasible and nonoptimal solutions. Examples show that the optimization method is able to successfully determine a set of optimal configurations with a minimum number of exchanger evaluations. Approximately 5 % of the pressure drop and channel velocity calculations and 1 % of the thermal simulations are required for the solution.

Aerodynamic Design Optimization of a Micro Radial Compressor of a Turbocharger

“…Figure 9 shows that even though each parameter did not equally affect the output parameters, each of them had reasonable effect on the efficiency. The following steps were implemented in the optimization method based on the created response surface: A screening optimization method which is usually used for preliminary designs The following steps were implemented in the optimization method based on the created response surface: A screening optimization method which is usually used for preliminary designs was selected to maximize the isentropic efficiency [27,29]. According to this method, three candidate points are obtained after generating 1000 samples.…”

Evaluación de un intercambiador de calor de placas para el enfriamiento de ácido acético

“…El diseño de las juntas y los puertos cerrados de las placas determinan el arreglo de flujo de los fluidos, el cual puede ser en paralelo, en serie o una de las varias combinaciones posibles de los dos. La distribución de flujo, el número de placas, el tipo de junta y la localización de la alimentación caracterizan la configuración del intercambiador (Pinto & Gut, 2002).…”

“…En este sentido (Opatril et al, 2016) presentaron un método de evaluación de un ICP basado en datos experimentales y el método gráfico de Wilson, con el fin de obtener el coeficiente de transferencia de calor y la caída de presión entre la entrada y salida de los fluidos. También (Pinto & Gut, 2002) propusieron un método de optimización para determinar la mejor configuración de un ICP, con el objetivo de seleccionar la configuración con la mínima área de transferencia de calor que aún satisfaga restricciones tales como el número de canales, la caída de presión de ambos fluidos, las velocidades del canal de flujo y la efectividad térmica del equipo.…”

An Experimental Assessment of the Plate Heat Exchanger Characteristics by Wilson Plot Method

“…The number of researchers experimentally investigated different plate patterns to describe their basic characteristics by newly developed criterial equations [3][4][5][6] and some researchers focused work on heat exchanger optimization, e.g. [7,8]. The presented work suggests a similar way but with the basic knowledge of the geometrical characteristics of plate patterns.…”
