A beginner is seeking help from the experts at Haichuan to translate a paper abstract
Thread Content
I’m in my senior year, and before completing my graduation project I need to translate a section of a paper. My skills in translation aren’t very good; I’ve done my best – using whatever methods I knew and carrying out all the tasks I could – but I still feel that the translation isn’t up to par. I’ve long known that there are many skilled people at Haichuan. I earnestly ask the experienced members of Haichuan to help me by translating the abstract in a as professional manner as possible. I would be extremely grateful. Design objectives for heat exchangers regarding minimum area and cost. MURALIKRISHNA and U. V. SHENOY, Department of Chemical Engineering and Computer-Aided Design Centre, Indian Institute of Technology, Bombay, India. A methodology is proposed to determine the feasible region for shell and tube heat exchanger designs using a pressure drop diagram. By taking into account both operational and geometric constraints, the feasible region is defined in such a way as to eliminate the need for trial and error during the design process. Each point on this diagram, representing the pressure drop on the shell side versus the tube side, corresponds to a unique design in terms of tube length, shell diameter, and baffle spacing. Additionally, curves can be plotted for designs that meet a specified heat exchange area or a certain total annual cost. Such curves enable the evaluation of various design options before proceeding with a detailed analysis of the exchangers, and they help establish design objectives aimed at achieving minimum area or cost. The area objective ensures that the exchanger has the smallest possible size while minimizing capital costs, whereas the cost objective results in optimal pressure drops by taking into account the trade-off between power consumption and exchanger area. This methodology is based on equations and can be easily implemented using computers. Keywords: shell and tube heat exchangers; cost targeting; cost-optimal design; minimum area design; capital-energy tradeoff; pressure drop diagram
Design of heat exchangers with minimum cost and minimum heat transfer area by K. MURALIKRISHNA and U. V. SHENOY, Department of Chemical Engineering and Computer-Aided Design Center, Indian Institute of Technology, Mumbai, India. A method for determining the feasible region for shell-and-tube heat exchangers on a pressure drop diagram is presented. Just as operational and geometric constraints are explained, defining the feasible region is intended to avoid repeated trials during the design process. Each point on the shell-tube (shell-to-tube) pressure drop diagram corresponds to specific values for tube length, shell diameter, and baffle spacing; furthermore, the precisely determined heat transfer area and the estimated annual cost can be indicated by specific curves. Such curves can provide various design options in the absence of detailed information on the heat exchanger, while also minimizing the cost and area of the heat exchanger design. The area target results in a heat exchanger of minimal size and lowest capital cost, while the cost target yields an optimal pressure drop that achieves a balance between energy consumption and heat exchange area. This methodology is an equation-based approach that can be easily implemented on computers. Keywords: shell-and-tube heat exchanger, cost planning, cost-optimized design, minimum area design, capital-energy tradeoff, pressure drop diagram. Last edited by lee142857 on 2009-3-23 16:32
Thank you, I’m really grateful. It’s much better than what I could translate
I feel it’s really unacceptable to still not be good at translation by my senior year
This is my first time translating a professional paper. We haven’t studied chemical engineering English; we only took bilingual courses in control systems, and this article is about equipment. I’m really impressed by that teacher who teaches bilingual courses; he translates the Chinese teaching materials in a way that reflects Chinese ways of thinking. When it comes to translating texts written by foreigners, there’s a huge difference in approach. I really realize now that professional English is very important, and it’s different from the CET-4 and CET-6 exams. So in the future, I need to learn from the experts at HaiChuan in order to master professional English as soon as possible.
How many college students these days focus on their studies while at school? I didn’t realize how important professional English is until I was about to graduate – is it too late? Is this article difficult?
A simple translation is as follows: Heat exchanger design objectives based on minimizing heat transfer area and cost. K. MURALIKRISHNA and U. V. SHENOY, Department of Chemical Engineering and Computer-Aided Design Centre, Indian Institute of Technology, Bombay, India. This paper proposes a methodology for determining the feasible region for the design of shell-and-tube heat exchangers using pressure drop diagrams. Through operational calculations and geometric constraints, this feasible region was defined during the design process to eliminate trial and error. In the pressure drop diagram, each point on the shell side relative to the tube side corresponds to a unique design of tube length, shell diameter, and plate spacing. Furthermore, the curves that can be drawn for these designs all correspond to a specific heat exchange area or a specific total annual cost. Before a detailed evaluation of the heat exchanger, these curves can reflect different design options, enabling the heat exchanger to achieve the goals of minimizing the heat transfer area or operating costs. The goal for the heat exchange area is to minimize the cost of the heat exchanger by ensuring minimal investment expenses, while the goal for operating costs is to achieve an optimal pressure drop by taking into account both energy losses and the heat exchange area. This balance-based methodology can be easily applied on computers.
It’s over; I’m about to be in my senior year, and it still feels quite challenging. Is it necessary for every undergraduate graduate to have the ability to understand and translate professional papers?
There is a question: is it better to be a generalist or a specialist? There have been calls suggesting that learning English wastes the youth of many students; some people could focus on research while others could work as translators. This world is too unfair. Why do we have to learn Chinese as well as English? Can’t it be the other way around? Those whose native language is English could learn Chinese and communicate in it, allowing us who don’t have any special skills to work as foreign teachers abroad.
English is very important – it’s experience that tells us this. No matter how much you complain, you’ll still have to say that English is important in the future
When looking for a job in my senior year, I kept complaining about why employers required a Level 4 certificate There are those that don’t use foreign equipment, and those that don’t communicate with foreigners. It was only after spending some time on the forum that I realized the importance of English; most chemical engineering software is developed by foreigners and does not have a Chinese version. To learn about cutting-edge things, you also need to use English.
