Determination of Characteristic Geometrical Parameters for the Design of Pillow‐Plate Heat Exchangers

Abstract

Thermoblech‐Wärmeübertrager sind eine vielversprechende Alternative zu konventionellen Apparaten. Zur Erstellung ihrer Dimensionierungsgrundlagen werden Daten zu charakteristischen Geometrieparametern benötigt, für die es in der Literatur bisher keine festgelegte Bestimmungsweise gibt. In dieser Arbeit wird die Geometrie der Thermobleche durch Verformungssimulationen exakt nachgebildet. Anschließend werden Näherungsgleichungen zur Geometriebestimmung hergeleitet und validiert. Darauf basierend werden Vorschläge zur orientierenden Ermittlung der charakteristischen Geometrieparameter abgeleitet.

Enlarged operation ranges for thermosiphon reboilers using pillow plates

“…The pillow plate heat exchanger was manufactured by DEG Engineering, Gelsenkirchen/Germany. All geometric data were determined according to the recommendations given in Piper et al (2014).…”

“…The main advantages of pillow plate apparatuses are the compact and light design and good heat transfer properties. They are used in the food industry for jacketed vessels or in the chemical industry as head condensers in columns (Mitrovic and Peterson, 2007;Tran et al, 2014;Piper et al, 2014).…”

Estimation of Efficiency Potentials Generated by Innovative Equipment Technologies

“…It plays an important role when calculating the installed material quantity to estimate the ecological expenditures of the apparatus. For this reason, the calculation of these characteristic parameters in a defined, transparent, and representative manner for the innovative apparatus technologies has to be enabled to allow a fair and accurate comparison to the state of the art, i.e., plain cylindrical tube HEX , .…”

Numerical Analysis of Header Structure Improvement in a Plate‐Fin Heat Exchanger

“…Experimental and computational fluid dynamics (CFD) methods have been extensively applied to investigate the flow distribution and pressure drop in heat exchangers [11][12][13][14][15]. Great efforts have been devoted concerning the flow uniformity in PFHE headers.…”
