“…The research found that pressure loss from helical baffles and vibrational stress might be reduced by using twin segmental baffles. Petinin and Dare [5] investigated triangular rotating shell-and-tube heat exchangers. The study found that triangular shell and tube heat exchangers are superior because they transmit more heat with the same amount of pressure loss.…”

The Heat Exchanger requires the least amount of initial investment and continuing maintenance while transferring energy at a maximum or minimum rate from a hot fluid to a cold fluid. With this technique, fluids are never mixed. Because they are used at high pressures and temperatures, Shell and Tube Heat Exchangers are always being improved in terms of efficiency and heat transfer rate. In this study, we suggest a design technique for a shell and tube heat exchanger that can increase the efficiency and rate of heat transfer. It consists of a tube, a tube inlet, a tube outlet, a shell, a shell inlet, a shell outlet, baffle plates, a circular tube bundle, and a baffle pitch. Three alternative pitches-Pitch-80, Pitch-60, and Pitch-40 with similar hot and cold water temperatures were taken into consideration when designing the heat exchanger described here. The helical baffle construction with Pitch Layouts is modified with varied specifications using Pitch-80, Pitch-60, and Pitch-40 and simulated with ANSYS R19.2 in the current invention (Fluent).

Widely known that, heat exchanger is a device that is being used to transfer thermal energy (enthalpy) between two or more fluids, between a solid surface and a fluid, or between solid particulates and a fluid, at different temperatures and in thermal contact. The most common heat transfer devices are concentric tube (double pipe), shell and tube and, plate heat exchanger. Nowadays, Shell and tube heat exchangers were used extensively in most industries as petrochemicals, oil and refineries. According to previous survey, almost 45% of heat exchangers utilized are shell and tube heat exchangers due to its highpressure application it is more suitable in the field of oil & petrochemical application. Thus, the following study presented shell and tube type only. Due to complexity of studying heat exchangers experimentally, Computational Fluid Dynamics (CFD) used to simulate the effect of local surface heat transfer coefficients on the surfaces by aid of computer numerical calculation and graphical display. In addition, analysis of the physical phenomena involved in fluid flow and heat conduction would be presented in the following research paper with Comparative designs for shell and tube heat exchangers. The paper considered a review for the design of a shell and tube heat exchanger. A variety of heat exchangers are used in industry and in their products. The objective of this paper is to describe most of these heat exchangers in some detail using classification schemes and the basic design methods for two fluid heat exchangers. The design techniques of recuperators and regenerators. Therein, popular analytical techniques such as log mean temperature difference (LMTD) and effectiveness-number of transfer units (ε-NTU) were considered in the analysis. In the case considered herein, both LMTD and ε-NTU techniques yield the same exact results. Keywords-Heat Exchanger; Shell and tube heat Exchanger; parallel flow; counter flow; single pass shell and tube.

“…El principio básico de operación es muy simple ya que ambos fluidos a diferentes temperaturas son puestos en contacto cercano para efectuar el intercambio de calor, pero se previene su mezclado por medio de algún tipo de barrera metálica (haz de tubos). Se emplean deflectores o bafles en la coraza para dirigir el flujo del fluido y como soporte para los tubos, incrementando de esta manera la turbulencia del fluido y, con ello, la tasa de transferencia de calor [7]. Hasta la fecha varios autores han estudiado la operación y funcionamiento de condensadores.…”

La adecuada evaluación y posterior selección de un intercambiador de calor para una aplicación determinada es de suma importancia para llevar a cabo una operación de intercambio de calor eficaz y eficiente. En el presente trabajo se realizó la evaluación térmica de un intercambiador de calor de tubo y coraza para efectuar la condensación de de una corriente de etanol, utilizando para ello agua como refrigerante. También se realizó un estudio de sensibilidad con el fin de evaluar la influencia del incremento de tanto el caudal de alimentación del etanol como su temperatura de entrada sobre el porciento de área en exceso del intercambiador (%Aexc). Se obtuvo un valor del parámetro %Aexc de 24,23 %, lo cual indica que el intercambiador de calor propuesto puede emplearse satisfactoriamente para llevar a cabo el servicio de condensación requerido. El %Aexc disminuye con un aumento de tanto el caudal de alimentación de etanol como de su temperatura de entrada, lo cual indica que el intercambiador de calor propuesto puede manejar valores superiores tanto del caudal de alimentación (hasta 4200 kg/h) como de la temperatura de entrada de estés compuesto (hasta 100 °C).
